The ramdisk-functions overwrites user modified
/etc/modprobe.d/blacklist.conf with a single entry
"blacklist evbug". Due to this, ramdisk fails to recognise
the hardware/disks etc for which user has modified
/etc/modprobe.d/blacklist.conf.
The commit enables copying all the *.conf files under
/etc/modprobe.d to the ramdisk. It creates
a config file /etc/modprobe.d/blacklist-dib-ramdisk.conf
instead of overwriting /etc/modprobe.d/blacklist.conf.
Closes bug: #1492804
