tools/makemanifest.py: Fix build on Windows by adding .exe to mpy-cross.

miketeachman · dpgeorge · commit 8db5d2d1f13a · 2020-03-05T10:26:31.000+11:00
When using a manifest on Windows the reference to mpy-cross compiler was
missing the .exe file extension, so add it when appropriate.

Also allow the default path to mpy-cross to be overridden by the (optional)
MICROPY_MPYCROSS environment variable, to allow full flexibility on any OS.
