recipetool: create: separate LICENSE items with & by default

recipetool sets the LICENSE value based on licenses detected from the
source tree. If there are multiple licenses then they were being
separated by spaces, but this isn't actually legal formatting and if
you're using "devtool add" you get a warning printed when devtool
parses the recipe internally.

Earlier I had made a conscious decision to do it this way since it's up
to the user to figure out whether the multiple licenses should all apply
(in which case they'd be separated with &) or if there is a choice of
license (in which case | is the correct separator). However, I've come
to the conclusion that we can just default to & and then the ugly
warning goes away, and it's the safest alternative of the two (and most
likely to be correct, since it's more common to have a codebase which is
made up of code with different licenses, i.e. all of them apply to the
combined work).

I've tweaked the comment that we add to the recipe to explicitly state
that we've used & and that the user needs to change that if that's not
accurate.

Fixes [YOCTO #10413].
