[PATCH] regex/exhaust_test: skip flaky 'regcomp_too_big' testcase on all archs

This bug is still relevant and is failing on amd64 as seen here:
https://ci.freebsd.org/view/Test/job/FreeBSD-main-amd64-test/26868/testReport/lib.libc.regex/exhaust_test/regcomp_too_big/

I confirmed that it intermittently fails locally with the following command
(using 100 runs because it does pass the first few runs).

$ bricoler run freebsd-src-regression-suite --param freebsd-src:url=/usr/src
--param freebsd-src:branch= --param
freebsd-src-regression-suite:hypervisor=bhyve --param
freebsd-src-regression-suite:memory=4096 --param
freebsd-src-regression-suite:ncpus=2 --param
freebsd-src-regression-suite:parallelism=1 --param
freebsd-src-regression-suite:count=100 --param
freebsd-src-regression-suite:tests='lib/libc/regex/exhaust_test:regcomp_too_big'

I've attached a patch to skip this testcase against this PR for tracking.

NOTE to future triagers: do not close this bug until the test is fixed and
unskipped.
