Merge Cherry-pick: MountRule: Aligning behavior with apparmor_parser
Mount Rules with options in { remount, [make-] { [r]unbindable, [r]shared, [r]private, and [r]slave }} do not support specifying a source. This commit aligns utils implementation to apparmor_parser's, which prohibits having a both source and a destination simultaneously, instad of just prohibiting source.
Therefore, both `mount options=(unbindable) /a,` and `mount options=(unbindable) -> /a,` are now supported (and equivalent for apparmor_parser). However, `mount options=(unbindable) /a -> /b,` is invalid.
For the same reason, specifying a fstype in these cases is also prohibited.
Similarly, we prohibit to specify a fstype for bind mount rules.

Merge Handle mount events/log entries without class
audit.log entries for mount events don't always include `class=mount`,
but can still be the base for mount rules.
Change logparser.py to also consider `operation=mount` as a mount event.
Actually we already had such a log and profile in our collection
(testcase_mount_01), but since it existed years before MountRule was
implemented, it was excluded in test-libapparmor-test_multi.py.
Therefore we didn't notice that it failed to produce a profile rule when
MountRule was introduced.
Remove testcase_mount_01 from the list of known failures so that it gets
tested - and fix the syntax error in the hand-written
testcase_mount_01.profile.
Also add testcase_mount_02 which is a mount event without fstype,
srcname and class.

Merge Cherry-pick: MountRule: Relaxing constraints on fstype and completing AARE support
- Before this commit, fstype had to match a known fs. However, having and maintaining the exhaustive list of fstypes proved challenging (see !1195 and !1176). Therefore, we add support for any filesystem name.
- Completing AARE support for fstype (brace expressions like ext{3,4} are now supported).
