basename: drop last_component null check

Browse source 
Prepare for fixes to the suffix pruning.  Since last_component doesn't
document a possible null result in lib/basename-lgpl.h, and the current
code also doesn't appear capable of producing one, drop the check.

libguile/filesys.c (basename): drop check for last_component null result.
