install: Revert utimensat usage (r299850).

Browse Source 
This should fix the build on older stable/10, since install is a bootstrap
tool.

Pending a decision how to fix this properly, revert utimensat usage. Copies
with the -p option will again appear older than the original almost always,
but -p is not commonly used.
