[OE-core] [PATCH] image_types: Fix bmaptool support for RSS

[Tom Rini]

With RSS we need to ensure that when making a bmap image that the
python3 that we created is found via /usr/bin/env rather than the host
python3.  Otherwise we're relying on the build host to have bmaptool
support installed.

I played around with a few ways to try and fix this problem, and this
was the best I could come up with.  Once this is in we need this in pyro
as well as it's broken there too.
