[PATCH] tests: skip large filesystem tests on MacOS

[Andreas Dilger <adilger@dilger.ca>]

Skip tests that create large filesystem on MacOS, since HFS doesn't
have sparse file support and this causes testing to be uninterruptible
for minutes while mke2fs is writing to some large non-zero offset and
filling up the test filesystem.  Since most testing is done on Linux
this shouldn't cause a significant gap in testing coverage.

Tests skipped are d_dumpe2fs_group_only, m_bigjournal, m_hugefile,
t_iexpand_full, t_iexpand_mcsum, and t_uninit_bg_rm.
