[OE-core] [PATCH 2/2] blacklist.bbclass: Rename to OE_BLACKLIST and minor cleanup

[Mark Hatle]

Revise the handling from ANGSTROM_BLACKLIST to OE_BLACKLIST.  Preserved
references to ANGSTROM_BLACKLIST for compatibility with existing users.

Rearrange a bit of the code to avoid unncessary steps if the package does
not have a blacklist.

Change the message generation from a note to debug, adjust the SkipPackage
message from:

<distro> DOES NOT support <recipe> because <reason>

to:

Recipe <recipe> is blacklisted: <reason>
