Add --rebuilt-binaries-timestamp option

This option makes emerge ignore binaries that would have been used
for --rebuilt-binaries, if they are older than the given timestamp.
Binaries are only reinstalled if they have a newer BUILD_TIME than
the installed package (not only unequal) with this option.
