fs: Support nanosecond resolution in uv__fs_to_timespec

Browse Source 
Remove the microsecond truncation in uv__fs_to_timespec() function to enable
full nanosecond resolution support. The utimensat() system call already
supports nanosecond precision, so the artificial truncation to microseconds
is no longer necessary.

This allows file modification and access times to be set with full nanosecond
precision instead of being limited to microsecond resolution.

Fixes the TODO comment about removing the microsecond resolution limit.
