Makefile.inc: Rewrite $(files-in-dir)

The $(files-in-dir) macro is supposed to return all files (out of a
given set) that reside directly (non-recursive) in a given directory.
While the current solution worked splendidly, we can achieve the same
without recursive macros that look at each parent dir individually.

This also fixes a future make error, as make doesn't like the variable
name ` ` anymore ;)
