dev-util/tinyxxd: fix KEYWORDS, symlinking, package collisions

KEYWORDS are now right below SRC_URI inside the else statement, for
both, live ebuild and versioned ebuild (effectively avoiding to diverge
the live ebuild from the versioned ebuild)

`dosym "$(which tinyxxd)" /usr/bin/xxd` required tinyxxd to be installed
which was an oversight on my part, it should be now fixed because i used
/usr/bin/tinyxxd

also added dev-util/xxd as a blocker to avoid file collisions
