Cleanup package dependencies, incremental build and unit testing scripts
* Removed stale dependency / use of fakeroot unit test invocation.
* Separated incremental build and unit test invocation from
gen_coverage_html.sh into their own scripts.
* Added checks for required binaries in gen_coverage_html.sh.
* Renamed setup_dev_packages to have a .sh suffix, for uniformity. Also
requires that it installs packages regardless of whether or not
they're already installed; this is to prevent a situation where
packages were removed from the portage tree but happen to still live
in the local chroot, so the discrepancy goes unnoticed (for example,
sys-apps/fakeroot and dev-util/lcov).
* Cosmetics: switched to long options when applicable, for clarity.
BUG=None
TEST=Update engine builds, tests, and coverage generation correctly
invoked
