Make the LD_PRELOAD path absolute in the tests that use it

In some situations, libtool will change directories and perform
a link step before executing the libtest test app. Since
LD_PRELOAD is in effect for this entire process, the path to the
binary must be absolute so it will be valid no matter in which
directory the app is running.
