When mounted via /etc/fstab like this,
/a /b fuse.gocryptfs default 0 0
we always get extra options passed. As reported by @mahkoh
at https://github.com/rfjakob/gocryptfs/pull/233 :
mount passes `-o noexec` if `-o user` is set and `-o exec` is not set.
If both `-o user` and `-o exec` are set, it passes `-o exec`.
Make these options work, and in addtion, also make -suid and -rw
work the same way.
