sci-mathematics/glpk: don't install build artifacts with USE=examples.

The build system for glpk automatically descends into the "examples"
directory to build an example program. Afterwards, when we install
the entire "examples" directory to honor USE=examples, we wind up
installing the build artifacts for that program as well.

This commit adds an extra "emake clean" to remove the build artifacts,
and an "rm" to get rid of the (useless, to the end user) example
Makefiles themselves.
