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.

Beside providing better readability, this also fixes a future make
error, as make doesn't like the variable name ` ` anymore ;)
