fix(coreos): Get version from manifest, export COREOS_ names

The version will now be tracked in the manifest so the old
coreos_version.sh needs to source it from there. Also export variables
with a COREOS_ prefix in addition to CHROMEOS_ since the latter name
isn't really correct. This is particularly true for the data published
via lsb_release.
Merge pull request #47 from marineam/version

fix(coreos): Get version from manifest, export COREOS_ names
fix(config): Remove make.conf options that duplicate profile defaults.

We were already using the default for CFLAGS, etc. LDFLAGS had
--as-needed but that has gone into the default Gentoo profile so we
ought to move it there as well. Also, ld's -O1 and -O2 are equivalent so
use the profile default -O1.
