filesystems: add new category for file systems and related utilities

The filesystems category houses file systems and file system utilities.
It is added mainly to turn the sysutils/fusefs-* pseudo-category into
a proper one, but is also useful for the sundry of other file systems
related ports found in the tree.

Ports that seem like they belong there are moved to the new category.
Two ports, sysutils/fusefs-funionfs and sysutils/fusefs-fusepak are
not moved as they currently don't fetch and don't have TIMESTAMP set
in their distinfo, but that is required to be able to push a rename
of the port by the pre-receive hook.

+SETUP BEFORE FIRST USE:
+- Create the log file /var/log/zrepl.log:
+  # service newsyslog restart
+- Teach syslogd to redirect facility local0 to the zrepl.log file:
+  # service syslogd reload
+- Modify the %%PREFIX%%/etc/zrepl/zrepl.yml configuration file
+- For remote backups, create the SSH key pair and authorized_keys file
+- Enable the zrepl daemon to start automatically at boot:
+  # sysrc zrepl_enable="YES"
+- Start the zrepl daemon:
+  # service zrepl start

+DANGER - SNAPSHOT PRUNING REQUIRES EXPLICIT KEEP RULES:
+For any ZFS snapshot that you want to keep, at least one rule must match.
+This also applies to snapshots taken by means other than zrepl
+(e.g. snapshots taken manually or via boot environment tools).
+
+In order to automatically warn the operator of impending certificate
+expiration, add this line to /etc/periodic.conf:
+
+    weekly_zrepl_enable="YES"
+
+More config details in the zrepl periodic script:
