libgomp.c-c++-common/pr109062.c: Fix expected spin count for hybrid x86
On my system with E and P cores (hybrid) x86, the spincount is by default 1
and not 300000, cf. PR109812 and r14-4571-ge1e127de18dbee.
Hence, this commit updates the expected value of the testcase to also
accept omp_display_env showing "GOMP_SPINCOUNT = '1'" - but only for
x86-64, which might be hybrid.
libgomp/ChangeLog:
* testsuite/libgomp.c-c++-common/pr109062.c: Update dg-output
to also accept GOMP_SPINCOUNT = 1 for x86-64.
