Use RTLD_LOCAL for symbol resolution
RTLD_LOCAL is the default value for symbol visibility flag of dlopen()
in Linux and NetBSD. Using it avoids conflicts during symbol resolution.
This also allows us to detect xlators that have not been explicitly
linked with libraries that they use. This used to go unnoticed
when RTLD_GLOBAL was being used.
BUG: 1193929
