[PATCH modular 2/4] build.sh: use the script name only, not the path in usage statement

[Gaetan Nadon]

If invoked from $PREFIX you currently you get:
Usage: util/modular/build.sh [options] prefix

Where you should always get:
Usage: build.sh [options] prefix

The path name is not part of the usage. The GNU compiler and
associated tools do not use the path.
