This prevents these tests from being compiled with ASAN since the asan
interceptors also define opendir() but matching the libc function.

The new PRELOAD_FDS variable accepts a list of file descriptors
that should be loaded into the process.
This may be used to optimize a loading process - in the case when
we already have a file descriptor to the library; we don't have
to look into multiple PATH to find it.
It may also be used in capability mode to load a single additional
library without the need to open a directory that contains it.
The last use of this functionality t may be a race-free method
of loading libraries.

build time by using atf_tc_get_config_var(tc, "srcdir"))
This will allow end-users to move the binaries to different locations
after they've been built without having to rebuild the binaries with
the new paths

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.
