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.

Reasons:
* Port build shouldn't use cross-compilation mode
  because it buids for the same architecture.
* RUSTFLAGS isn't passed to the build of all or some Rust ports
  in the cross-compilation mode.

Essential changes:
* Remove the CARGO_BUILD_TARGET make variable.
* Remove CARGO_BUILD_TARGET and CARGO_TARGET_* from CARGO_ENV.
* Update many ports that used CARGO_BUILD_TARGET.
* Build paths now don't include the architecture triplet part.

Immadiate benefits:
* Unbreak build on architectures like i386 that sometimes require
  special RUSTFLAGS that were not effective in the cross-compilation
  mode.

Ports that really need cross-compilation for some reason should
enable it on case-by-case basis. Example: net-p2p/cncli
(Not sure why does net-p2p/cncli actually need it, but it only
builds with these options.)
