9p: remove support for the "handle" backend

The "handle" fsdev backend was deprecated in QEMU 2.12.0 with:

commit db3b3c7281ca82e2647e072a1f97db111313dd73

    9pfs: deprecate handle backend

    This backend raise some concerns:

    - doesn't support symlinks
    - fails +100 tests in the PJD POSIX file system test suite [1]
    - requires the QEMU process to run with the CAP_DAC_READ_SEARCH
      capability, which isn't recommended for security reasons

    This backend should not be used and wil be removed. The 'local'
    backend is the recommended alternative.

It has passed the two release cooling period without any complaint.

Remove it now.
