section-select: Fix performance problem (PR30367)

when using many wild-statements with non-wildcard filenames we
were running into quadraticness via repeatedly using lookup_name
on a long list of loaded files.  I've originally retained using
lookup_name because that preserved existing behaviour most obviously.
In particular in matching wild-statements when using a non-wildcard
filename it matches against local_sym_name, not the filename member.
If the wildspec would have an archive-spec or a wildcard it would use
the filename member, though.  Also it would load the named file
(and ignore it, as being not equal to the currently considered
input-statement).

Rewrite this to not use lookup_name but retain the comparison
against local_sym_name with a comment to that effect.

	PR 30367
	* ldlang.c (walk_wild_section_match): Don't use lookup_name
	but directly compare spec and local_sym_name.
