run_tests.sh: don't crash on absolute filepaths in test names.

This patch fixes bug #137 "run_tests.sh fail when running configure
script with absolute path".

The fix: copy all test files into temporary build directory (which
is addressed by a relative filepath) and keep messing with relative
filepaths.
