Change binary path in libc test cmake file from relative to absolute

[amykhuang]

For some reason cmake usually turns this path into an absolute path, but sometimes
it doesn't do it and stays as a relative path, which means the command will fail.
Specify it as an absolute path always so this doesn't happen any more.

Changes

For some reason cmake usually turns this path into an absolute path, which works, but sometimes
doesn't. Force it to be an absolute path always.
