intel-microcode: bump version to 20150121

Bumped version to 20150121. Dropped runtime dependency on iucode-tool
which is used to generate the cpio or trim down the data file based on
your CPU. While it can also be used to load the microcode that is not
the recommended method for Linux 3.9 and newer instead you should use
the kernel's built-in early microcode loading facilities.

+DESCRIPTION = "The microcode data file contains the latest microcode\
+ definitions for all Intel processors. Intel releases microcode updates\
+ to correct processor behavior as documented in the respective processor\
+ specification updates. While the regular approach to getting this microcode\
+ update is via a BIOS upgrade, Intel realizes that this can be an\
+ administrative hassle. The Linux operating system and VMware ESX\
+ products have a mechanism to update the microcode after booting.\
+ For example, this file will be used by the operating system mechanism\
+ if the file is placed in the /etc/firmware directory of the Linux system."
