Update debug_qf_expand_symtabs_matching to use typedefs.

Update debug_qf_expand_symtabs_matching to use typedefs.

Commit 206f2a5777679e6d1ad21ce435f6e7af92e2d41a added two new
typedefs, but did not update debug_qf_expand_symtabs_matching
to use them.  This patch fixes this.

Checked in as obvious.

	* symfile-debug.c (debug_qf_expand_symtabs_matching):
	Use expand_symtabs_file_matcher_ftype and
	expand_symtabs_symbol_matcher_ftype.
