MDEV-30855 Remove test galera.galera_bf_abort_group_commit

This test was re-enabled in commit 0174a9ff, and
has been failing since then.
The test is configured such that Galera runs with commit ordering
disabled, a configuration which is which was meant for testing the
performance penalty of commit ordering (not meant to be used in
practice).
Moreover, we have test galera_sr.galera_sr_bf_abort, which is
identical, but runs with commit ordering enabled.
No reasons to keep the failing test around.
