kernel: e100: take e100 firmware from linux-firmware repository

The firmware directory in the Linux kernel was removed in kernel 4.14,
take the e100 firmware files now from the linux-firmware repository
instead. To do so create the new package e100-firmware. This will also
work with older kernel versions.
