x11-plugins/astime: new EAPI=6 revision that respects LDFLAGS.

This new revision is based on the ebuild submitted by Michael
Mair-Keimberger, with additional updates for EAPI=6. I have also
simplified the patch that we apply; now it contains only the addition
of LDFLAGS to the linker command. By side-stepping upstream's "make
install" target, we avoid having to patch in DESTDIR and all of that.
Doing so actually simplifies src_install() a bit, as it can be reduced
to a dobin, newman, and dodoc.
