Minor improvements to build

Exclude source files in libbb that aren't used by busybox-w32.  This
speeds up the build marginally.  They can always be reinstated if
necessary.

Provide fake routines for everything in inode_hash.c so that it
can be excluded.  inode_hash.c is now unchanged from upstream.

Use last_char_is in has_exe_suffix_or_dot.  It doesn't save any
bytes but it makes the code neater.
