OECore license fixes: meta/*

This is a quick audit of only the most obviously wrong licenses
found within OECore. These fixes fall into four areas:

- LICENSE field had incorrect format so that the parser choked
- LICENSE field has a license with no version
- LICENSE field was actually incorrect
- LICENSE field has an imaginary license that didn't exist

This fixes most of the LICENSE warnings thrown, along with my prior
commit adding additional licenses to common-licenses and additional
SPDXLICENSEMAP entries.

HOWEVER..... there is much to be done on the license front.
For a list of recipes with licenses that need obvious fixing see:

https://wiki.yoctoproject.org/wiki/License_Audit

That said, I would suggest another license audit as I've found
enough inconsistencies. A good suggestion is when in doubt, look at
how openSuse or Gentoo or Debian license the package.
