syscall: drop fallback to utimes in UtimesNano on Linux
The minimum required Linux kernel version for Go 1.18 will be changed to
2.6.32, see #45964. The current minimum required version is 2.6.23 and
utimensat was added in 2.6.22, so the fallback isn't even necessary for
the current minimum supported version. Remove the fallback to utimes.
For #45964
