[layerindex-web][PATCH] import_layer.py: support import layer to non-master branch

[<changqing.li@windriver.com>]

From: Changqing Li <changqing.li@windriver.com>

Before this commit, it only support create layer on master branch,
support import layer to other branch to fix following issue:

For layer A, it only works on NON-MASTER branch. If we import
it use this tool, it will by default import it to master branch.
In master branch, bitbake is newer, and use new overrides style, but
layer A use old style overrides style, which make update.py -b
master report error:
INFO: Collecting data for layer A on branch master (NON-MASTER)
NOTE: Starting bitbake server...
ERROR: Variable PREMIRRORS_append contains an operation using the old override syntax. Please convert this layer/metadata before attempting to use with a newer bitbake.
ERROR: Traceback (most recent call last):
