Subject: [PATCH 1/3] Filesystem: Fix OpenBSD check in fstype_supported()
fstype_supported() is supposed to skip the /proc/filesystems check if
the OS is OpenBSD. Instead, it skips the check if the OS is **not**
OpenBSD. That means the function has been a no-op for all other distros.

Subject: [PATCH 2/3] Filesystem: Improve fstype_supported logs for fuse
Make it more clear when we have to use a different name to check for
support of a particular filesystem. Currently only used for fuse-type
filesystems.

Subject: [PATCH 3/3] Filesystem: Add support for Amazon EFS mount helper
mount.efs, the mount helper for Amazon Elastic File System (EFS)
provided by amazon-efs-utils [1], is a wrapper for mount.nfs4. It offers
a number of AWS-specific mount options and some security improvements
like encryption of data in transit.
This commit adds support by treating an fstype=efs like fstype=nfs4 for
the most part.
Resolves: RHBZ#2049319
