Damien George 4cdcbdb753 tests/thread: Make exc1,exit1,exit2,stacksize1,start1 tests run on rp2.
The RP2040 has 2 cores and supports running at most 2 Python threads (the
main one plus another), and will raise OSError if a thread cannot be
created because core1 is already in use.  This commit adjusts some thread
tests to be robust against such OSError's.  These tests now pass on rp2
boards.
