These 2 test cases are added to cover the normal using scenes of
gettimeofday().
They have been used to trigger and fix up such issue with nolibc:
nolibc-test.c:(.text.gettimeofday+0x54): undefined reference to `__aeabi_ldivmod'
This issue happens while there is no "unsigned int" conversion in the
coming new clock_gettime / clock_gettime64 syscall path of
gettimeofday():
tv->tv_usec = ts.tv_nsec / 1000;
