Fixed: bug serving files because of LUA exception

"Interrupted system call" during PWDIR change on "popen" function
Restored by removing FIND's wildcard which could yield fo emptiness
(example : `mydir/` is empty; making `cd mydir && find *` yielding
to non argumented FIND function.

Tested on Stretch with nginx (1.10.3-1+deb9u2) and lua5.1 (5.1.5-8.1+b2).

Note that this could lead to bugs, code refactor should enclose lua-filesystem (1.6.3-1),
but I'm a rookie in LUA.
