Unbreaking ejabberd on SELinux again

[dasyatid1]

On a tiny Fedora server, judging by the journalctl output and audit2allow:

allow ejabberd_t self:process execmem;
allow ejabberd_t tmpfs_t:file write;

I know BEAM's recently gotten a JIT, so I expect that explains the first one. I'm not sure why the second wasn't already allowed by a broader policy cluster.
