rootfs-postcommands.bbclass: improve binary reproducibility
Conditionally support binary reproducibility of rootfs images.
If REPRODUCIBLE_TIMESTAMP_ROOTFS is specified then:
1. set /etc/timestamp to a reproducible value
2. set /etc/version to a reproducible value
3. set /etc/gconf: set mtime in all %gconf.xml to reproducible values
The reproducible value is taken from the variable REPRODUCIBLE_TIMESTAMP_ROOTFS.
