[PATCH] bitbake-layers: fix Python error during parse

[Paul Eggleton <paul.eggleton@linux.intel.com>]

If "bitbake-layers show_layers" was run when the cache was dirty forcing
a parse, it failed with the following error:

ERROR: Failure expanding variable SRCPV, expression was
${@bb.fetch2.get_srcrev(d)} which triggered exception AttributeError:
'module' object has no attribute 'fetch2'

A simple import of bb.fetch2 in bitbake-layers fixes this.

Fixes [YOCTO #1855].
