Switch from 'vmail' to leap-mx's user/group (#6936, #7639)

This change will make sure that the user/group for leap-mx exist, and it
changes the mail location from /var/mail/vmail to the more helpful name
/var/mail/leap-mx.

This change requires:

https://github.com/leapcode/leap_mx/pull/78

and it would replace merge request:

https://github.com/leapcode/leap_mx/pull/65

and fix https://leap.se/code/issues/6936 and
https://leap.se/code/issues/7635
