linux: Add y2106 support on utimensat tests
The tests are refactored to use a common skeleton that handles whether the underlying filesystem supports 64 bit time, skips 64 bit time tests when the TU only supports 32 bit, and also skip 64 bit time tests larger than 32 unsigned int (y2106) if the system does not support it (MIPSn64 on kernels without statx support). Checked on x86_64-linux-gnu and i686-linux-gnu. I also checked on a mips64el-linux-gnu with 4.1.4 and 5.10.0-4-5kc-malta kernel to verify if the y2106 are indeed skipped.
