Add a new make target to build an rpm. This uses rpmbuild --build-in-place,
so no SRPM is created.
Also clean up the specfile to remove manually-added Requires: that will
be auto-generated, add a couple new BuildRequires: and use macros for
file locations.

bcachefs-tools has both libscrypt and libsodium as build dependencies,
but libsodium already includes the same scrypt implementation as libscrypt,
originally written by Colin Percival.
Use the libsodium copy, dropping the extra libscrypt dependency.
Explicitly adopt the default scrypt N, r and p values from libscrypt to
avoid unintended changes in the default work parameters for bcachefs.
