Make jq_get_lib_dirs return an empty array if JQ_LIBRARY_PATH is not set

For the jq_state used by the jq utility, the JQ_LIBRARY_PATH attribute
will always be set, but, in general, it is possible that it might not
be.

If it is not set, jq_get_lib_dirs() will return jv_invalid().

That is not good, because some code in linker.c expects it to always
returns an array.

This patch makes jq_get_lib_dirs() return an empty array if
JQ_LIBRARY_PATH is not set to prevent problems.

This issue made OSS fuzz trigger failed assertions every time it tried
to compile a script that uses "include".
