Disable LDSO_SAFE_RUNPATH (b/28440753)

This is a workaround to the fact that uClibc-ng 1.0.12 (arguably) does
not treat RPATHs correctly. It does not expand $ORIGIN in a parent
executable's RPATH when doing a dlopen() inside a shared library. The
previous uClibc (0.9.33) also did not do this, but it did allow relative
paths for LD_LIBRARY_PATH which was sufficient for the use-case Fiber
has. That behavior is now hidden behind !LDSO_SAFE_RUNPATH, thus this
patch.

Note that LDSO_SAFE_RUNPATH, despite the name, has no known security
implications - it only protects you against accidental double-loading of
libraries via different relative paths.
