gnu-efi: remove obsolete patch

The original patch in 2013[1] did this:

+-libefi.a: libefi.a($(OBJS))
++libefi.a: $(OBJS)

The Makefile no longer uses this syntax and simply replacing $^ with
$(OBJS) is a no-op, so this patch isn't needed.

-Subject: [PATCH] Fix parallel make failure for archives
-
-Upstream-Status: Pending
-
-The lib and gnuefi makefiles were using the lib.a() form which compiles
-and ar's as a pair instead of compiling all and then ar'ing which can
-parallelize better. This was resulting in build failures on larger values
-of -j.

-See http://www.chemie.fu-berlin.de/chemnet/use/info/make/make_toc.html#TOC105
