conformtest: Fix XPG standard naming.

The conform/ tests test -D_XOPEN_SOURCE under the name "XPG3", and -D_XOPEN_SOURCE -D_XOPEN_SOURCE_EXTENDED under the name "XPG4". That naming is misleading. _XOPEN_SOURCE_EXTENDED actually means XPG4.2, including UX-shaded interfaces. _XOPEN_SOURCE actually means XPG4, or XPG4.2 without UX-shaded interfaces. (Prior XPG versions also used _XOPEN_SOURCE, but without any versioning of the values of the macro, so XPG4.2 without UX-shaded interfaces is the only sensible set of interfaces for glibc to expose given _XOPEN_SOURCE=1 without _XOPEN_SOURCE_EXTENDED defined.) This patch fixes the naming in the conform/ tests, so that what is now called XPG4 is changed to XPG42, and what is now called XPG3 is changed to XPG4. Tested for x86_64 (and verified the complete set of expectations is unchanged by the patch beyond the intended renaming). * conform/GlibcConform.pm (XPG4): Rename standard to XPG42.
