allow skipping mux permission check

Browse Source 
When using WSL, we want to place the unix socket on NTFS and that
reports an insecure set of permissions which cause us to refuse
to start up.

As a bit of a gross hack, allow skipping that check by setting an
environmental variable:

```
WEZTERM_SKIP_MUX_SOCK_PERMISSIONS_CHECK= wezterm start --front-end muxserver
```

that works best in conjunction with this in the WSL `.wezterm.toml`
file: (swap `wez` with your username):

```
mux_server_unix_domain_socket_path = "/mnt/c/Users/wez/.local/share/wezterm/sock"
```
