sys-apps/mawk: import from upstream Gentoo

Now that the /usr/bin/awk symlink has moved to the chromeos-base package,
we can move to the unmodified upstream Gentoo ebuild.

BUG=chromium-os:21900
TEST=`emerge chromeos-base` and see /usr/bin/awk -> gawk
TEST=`emerge-amd64-generic mawk` and see /usr/bin/awk -> mawk
TEST=`emerge-arm-generic mawk` and see /usr/bin/awk -> mawk
TEST=`emerge-x86-generic mawk` and see /usr/bin/awk -> mawk
