Test RTLD's new LD_LIBRARY_PATH_FDS variable.

Test LD_LIBRARY_PATH_FDS by linking a binary that requires a shared
library that isn't in any of the usual search paths.  Ensure this fails
when we don't supply LD_LIBRARY_PATH_FDS or we pass invalid information
in it.  Ensure it works when we pass the correct directory in various
places in the variable.
