Correctly generate libexecdir based path for the bcachefsck_all
service, like the bcachefsck_all_fail service already does.

this gets us back down to a single fd for opening block devices, which
means we can use O_EXCL.

not needed with pwritev2(.., RWF_SYNC), and perhaps we can get down to
one fd and then use O_EXCL for block devices.

The bcachefs sub-commands that are implemented in Rust (completions,
list, and mount) had separate entrypoints and thus had some differences
in behavior.
This introduces a common entry point for the Rust sub-commands. This
reduces duplicate boilerplate code like parsing argv and setting up
logging, and will facilitate converting more sub-commands to Rust in
the future.
An immediate benefit is that this fixes an issue with `bcachefs list`
not reporting errors:
before:
$ bcachefs list /dev/typo
$ echo $?
0
after:
$ bcachefs list /dev/typo
ERROR - bcachefs_rust::cmd_list: Fatal error: "No such file or directory"
$ echo $?
1

These are executables that need to be installed in a non-path location.
Most distributions now install these into /usr/libexec, and the
path variable for this is LIBEXECDIR, so use that instead.
This adds a new option to cmd_fsck for using the kernel implementation
of fsck instead of userspace, via the BCH_IOCTL_FSCK_OFFLINE ioctl.
This isn't intended for normal usage - mainly for testing and debugging
purposes, and for when the kernel version of bcachefs better matches the
on disk format version.

Specifically, do not recursively expand $(CFLAGS) because this leads to
repeatedly performing compile tests (e. g. cc-disable-warning) on every
recipe execution.

This should use `cargo clean` instead of `rm -rf ...`. Also,
due to a typo, the `rm` did not actually remove the Rust artifacts.

This adds on to 446ec6b092 ("docs: mention that libclang is
required"). That commit updated the dependency list for Debian. This
adds the packages needed to get llvm-config for arch and fedora.

passing a parent closure is totally unnecessary when using
BCH_WRITE_SYNC - and pops an assert in debug mode, because the write
path no longer supports delivering completions that way.

now that we have
- shrinkers running in the background via a thread
- run_shrinkers() considering swap usage
this can probably be safely dropped - and it causes problems when
running as non root, so let's do so.
