Move DISTUTILS_USE_SETUPTOOLS check from distutils-r1.eclass to install QA checks, and rewrite it to use installed egg-info rather than greps on input files. This produces less false positives, particularly in packages that use boilerplate empty 'entry_points' in their setup script or configuration file.
We also no longer require explicit setuptools RDEPEND for packages using other entry point types than console_scripts -- instead, we assume that the package consuming these entry points will bring setuptools as necessary. The rough idea is to look at egg-info metadata installed by distutils or setuptools. Plain distutils installs it as a regular file, while setuptools as a directory, and that's how we distinguish the two. For setuptools, we additionally grep entry_points.txt for `[console_scripts]`, and require RDEPEND when they are present.
