[OE-core] [PATCH 26/33] wic/engine.py: Load paths from PATH environment variable

[Armin Kuster]

From: William Bourque <wbourque at gmail.com>

Load self.paths from environment variable and
if it fails, fall back to hardcoded list.
This is required for users that would need to load
different e2fsprogs binaries if their system's ones
are not recent enought
