Rule mount_option_boot_noauto breaks checking of other mount options in /boot

#### Description of problem:
When rule `mount_option_boot_noauto` is remediated, `/boot` is not mounted by default.
In this situation, the rules `mount_option_boot_noexec` and `mount_option_boot_nosuid` fail check and remediate properly.

#### Actual Results:
The checks expect that the partition is mounted and has the options.

#### Expected Results:
When `noauto` option is set, the check should allow the partitions not to be mounted.
The check for mount options should be done via filesystem configuration, probably via `/etc/fstab`.
