Set a default PATH if PATH is empty or unset

mount(1) unsets PATH before calling mount.fuse. Therefore it's not set
in gocrpytfs either and daemonization fails if gocryptfs was not
executed via an absolute path.

mount.fuse handles this by leaving the execution of the helper to
/bin/sh. /bin/sh handles an empty PATH by searching a few default

This patch sets the PATH to a sane default if it's empty or unset.
