Fix thinkos in DW_FORM_strx detection in configure.ac

My patch "568dee1 PR25042 - Support string form DW_FORM_strx{1,4} from
DWARF 5" introduced a thinko in configure.ac.  The thinko triggers a
regression test issue on old systems where we don't support
DW_FORM_strx from DWARF 5.  Fixed thus.

	* configure.ac: Fix thinko when setting the HAVE_DW_FORM_strx
	macro.
