init/Kconfig: lower GCC version check for -Warray-bounds
We continue to see false positives from -Warray-bounds even in GCC 10,
which is getting reported in a few places[1] still:
security/security.c:811:2: warning: `memcpy' offset 32 is out of the bounds [0, 0] [-Warray-bounds]
Lower the GCC version check from 11 to 10.
