rootfs-postcommands.bbclass: make opkg status reproducible

opkg stores the current time as Installed-Time in its status file when
installing packages to the rootfs. Make this reproducible by replacing
Installed-Time with ${REPRODUCIBLE_TIMESTAMP_ROOTFS}, which then also
matches the files' datestamps.

Based on OpenWrt's approach for the issue [1].
