Only a few ports have TCP/IP loopback enabled in their network stack, and this test will only pass on those ports. There's not really any good way to do a feature check for loopback mode without actually running the test and seeing if it passes/fails, so add an explicit check that the test is running on a port known to support loopback. (Enabling loopback on lwIP, eg RPI_PICO_W, costs +568 code and +272 bss and is a rarely used feature, so not worth unconditionally enabling.) Signed-off-by: Damien George <damien@micropython.org>

Summary
Only a few ports have TCP/IP loopback enabled in their network stack, and this test will only pass on those ports. There's not really any good way to do a feature check for loopback mode without actually running the test and seeing if it passes/fails, so add an explicit check that the test is running on a port known to support loopback.
(Enabling loopback on lwIP, eg RPI_PICO_W, costs +568 code and +272 bss and is a rarely used feature, so not worth unconditionally enabling.)
Testing
Tested on RPI_PICO2_W, this test now skips.
Tested on unix port and ESP32_GENERIC, this test still runs and passes.
