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

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.
