[PATCH] Makefile: determine the list of header files using a glob

[Johannes Sixt <j.sixt@viscovery.net>]

From: Johannes Sixt <j6t@kdbg.org>

The list of header files was incomplete because a number of header files
were added to the code base, but were not added to the list LIB_H that we
have in the Makefile. This meant that no rebuild was triggered if one of
the missing headers was changed because we do not have automatic
dependency tracking, either.

Sidestep the issue by computing the list using $(wildcard).
