[libc++] Mark local_time test as a long test

[ldionne]

It can otherwise timeout under some slow configurations.

@vitalybuka Where is the CMake cache that you use for your hwasan bot? It needs to be updated similarly.

[mordante]

Thanks for working on this! LGTM modulo one request.

[ldionne]

@vitalybuka If we check this in without also updating your bot configuration, it'll break again since we're removing the UNSUPPORTED: hwasan annotation in the test.

I have enabled the flag on our build bots, so it's safe to land.

@vitalybuka vitalybuka force-pushed the review/sanitizers-long-tests branch from 4e2bdd2 to 8202a5e

It was rebase just to trigger CI, as many steps failed.
