texlive-common.eclass: Add TEXLIVE_SCRIPTS_W_FILE_EXT variable

Browse Source 
Some scripts are supposed to be installed with file extensions [1, 2]. Add
support for declaring those scripts in a new elcass variable
TEXLIVE_SCRIPTS_W_FILE_EXT.

Also use pure-bash functions to retrieve the basename and strip the file
extensions. And use "declare -l" to lowercase the value of 'trg',
instead of 'tr' [3].
