MountRule: sync flags_keywords with parser code

... based on /mount.cc mnt_opts_table

Several keywords and aliases were missing in flags_keywords:
- B
- M
- make-private
- make-rprivate
- make-rshared
- make-rslave
- make-runbindable
- make-shared
- make-slave
- make-unbindable
- r
- R
- read-only
- w

Also sort the keywords in the same order as in mount.cc.

Note: AARE handling is still a TODO.

After that, update the list of known parsing failures:
- several valid profiles are now correctly parsed
- some `"make-*" mount opt and an invalid src` bad profiles are no
  longer detected as being invalid
