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.

+Ntfs2btrfs is a tool which does in-place conversion of Microsoft's NTFS
+file system to the open-source file system Btrfs, much as btrfs-convert
+does for ext2.  The original file system image is saved as a reflink copy
+at `image/ntfs.img', and can be deleted to free up space if you want to
+keep the conversion.
