testsuite: xfail test for short_enums

On arm-none-eabi, the test case fails with
.../null-deref-pr108251-smp_fetch_ssl_fc_has_early-O2.c:63:65: warning: converting a packed 'enum obj_type' pointer (alignment 1) to a 'struct connection' pointer (alignment 4) may result in an unaligned pointer value [-Waddress-of-packed-member]

The error was fixed in basepoints/gcc-14-6517-gb7e4a4c626e, but it
was considered to be a too big change to be backported and thus, the
failing test is marked xfail in GCC13.

gcc/testsuite/ChangeLog:
	* gcc.dg/analyzer/null-deref-pr108251-smp_fetch_ssl_fc_has_early-O2.c:
	Added dg-bogus with xfail on offending line for short_enums.
