Damien George 1ded19d4b3 qemu-arm: Reinitialise uPy heap and runtime at start of each test.
Previous to this patch, all qemu-arm tests were running in the same
session, and global variables could be left over from the previous test.
This patch makes it so that the heap and runtime are reinitialised at
the start of each test.
