base.bbclass: show layer's branches/revisions in the banner info

The patch removes METADATA_BRANCH and METADATA_REVISION, and treats the meta/
in the same way as other layers.
In the case some layers belonging to the same repo, the branch and revision
are only printed once, but all the layer names are still printed.

An example output can be:

OE Build Configuration:
BB_VERSION        = "1.13.1"
TARGET_ARCH       = "i586"
TARGET_OS         = "linux"
MACHINE           = "emenlow"
DISTRO            = "poky"
DISTRO_VERSION    = "1.0+snapshot-20110702"
TARGET_FPU        = ""
meta
meta-yocto        = "dcui/banner_v3:4b712dba68a98c827b8f3d0242da9153c4f65473"
meta-emenlow
meta-sugarbay
meta-n450         = "dcui/test1:76d1178ba1a43cf6457c89717134aeb9f1275fae"
