syslinux: Fix syslinux_test in out-of-tree builds

Browse source 
syslinux_parse simplifies some filenames by removing things like ".."
segments, but the tests assumed that @abs_top_srcdir@ would be
untouched, which is not true in the case of out-of-tree builds where
@abs_top_srcdir@ may contain ".." segments.

Performing the substitution requires some awkwardness in Makefile.am due
to details of how config.status works.

syslinux_test: $(top_builddir)/config.status tests/syslinux/ubuntu10.04_grub.cfg
# Mimic simplify_filename from grub-core/lib/syslinux_parse.c, so that we
# can predict its behaviour in tests. We have to pre-substitute this before
# calling config.status, as config.status offers no reliable way to hook in
# a command between setting ac_abs_top_srcdir and emitting output files.
