test-lib: make $GIT_BUILD_DIR an absolute path

Browse source 
Change the GIT_BUILD_DIR from a path like "/path/to/build/t/.." to
"/path/to/build". The "TEST_DIRECTORY" here is already made an
absolute path a few lines above this.

We could simply do $(cd "$TEST_DIRECTORY"/.." && pwd) here, but as
noted in the preceding commit the "$TEST_DIRECTORY" can't be anything
except the path containing this test-lib.sh file at this point, so we
can more cheaply and equally strip the "/t" off the end.

This change will be helpful to LSAN_OPTIONS which will want to strip
the build directory path from filenames, which we couldn't do if we
had a "/.." in there.
