emacs: tramp: detect wrapped gvfsd-fuse daemon

Tramp checks for a running `gvfsd-fuse` process to figure out whether to enable
gvfs-based. Its `tramp-compat-process-running-p` function uses
`/proc/<pid>/comm` to check for the name of running process(es). In Nix, the
gvfsd processes are launched via wrappers and the name of `gvfsd-fuse` in
`comm` in Linux is `.gvfsd-fuse-wra` (truncated to 15 characters) which
means the process is not detected and `tramp-gvfs-enabled` ends up with
`nil` even when gvfs is available.

This patch adds `.gvfsd-fuse-wrapped` to the list of process names to check when
determining the value of `tramp-gvfs-enabled`.
