games/albion: Fix build with Automake 1.16

This has been broken since a while when Automake 1.16 was introduced in
NixOS/nixpkgs@e0c155e26b6a73bba06d6f2ced12bd4bcb0d6503.

The upstream WildMIDI project has since moved to CMake and the patches
from the static recompilation project haven't been ported to a newer
version, so we're stuck with the Automake variant.

Fortunately, the fix is rather easy and it's more obvious when you look
at the changelog of Automake 1.16:

  The 'subdir-object' option no longer causes object files corresponding
  to source files specified with an explicit '$(srcdir)' component to be
  placed in the source tree rather than in the build tree.

  For example, if Makefile.am contains:

      AUTOMAKE_OPTIONS = subdir-objects
      foo_SOURCES = $(srcdir)/foo.c $(srcdir)/s/bar.c $(top_srcdir)/baz.c

  then "make all" will create 'foo.o' and 's/bar.o' in $(builddir)
  rather than in $(srcdir), and will create 'baz.o' in $(top_builddir)
  rather than in $(top_srcdir).

So all we need to do is strip off the absolute pathname of
libWildMidi.la/libWildMidiA.la and the build passes.
