[testsuite] Remove strcmp-1.c XFAIL

[Richard Sandiford]

Earlier versions of the VxWorks kernel's strcmp function used signed
rather than unsigned comparisons.  This problem has been fixed in recent
versions (6.5 and 6.6), so is it OK to remove the XFAIL?  Tested on
i586-wrs-vxworks, mips-wrs-vxworks, sh-wrs-vxworks and sparc-wrs-vxworks.
