ubi: align galera comments, sticky bit for /run/mariadb

/run/mariadb should be able to be written by any user in
an unpriv mode, but that socket written there shouldn't be
deletable by anyone, so sticky bit restricts this to the creating
user.

Align comments around galera and clarify that its the deb/rpm
packaging differences that result in different locations.
