Fix test isolation for elf/tst-ifunc-fault-lazy, elf/tst-ifunc-fault-bindnow
Commit Message
Previously, ld.so was invoked only with the elf subdirectory on the
library search path. Since the soname link for libc.so only exists in
the top-level build directory, this leaked the system libc into the
test.

How about using rtld-prefix?
