[PATCH v2 01/13] selftests/nolibc: remove gettimeofday_bad1/2 completely

From: Zhangjin Wu
Date: Mon May 29 2023 - 15:47:02 EST

In the clock_gettime / clock_gettime64 syscalls based gettimeofday(),
there is no way to let kernel space 'fixup' the invalid data pointer of
'struct timeval' and 'struct timezone' for us for we need to read
timespec from kernel space and then convert to timeval in user-space
ourselves and also we need to simply ignore and reset timezone in

Without this removal, the invalid (void *)1 address will trigger a
sigsegv (signum = 11) signal and stop the whole test.
