test/py: Use aligned address for overlays in 'extension' test

The 'extension' test would set 'extension_overlay_addr' variable to
decimal 4096 due to conversion in python. The 'extension_overlay_addr'
is however sampled using env_get_hex("extension_overlay_addr", 0);
which converts the 4096 to 0x4096 and uses that as DT overlay address,
which is unaligned. Fix this by setting extension_overlay_addr to 0x1000
as intended, which is aligned.
