arch/x86: Do not run UPDATE-FIT if we don't include microcode

The original intention was to only run UPDATE_FIT when a microcode file was
included in CBFS. This happens when either CPU_MICROCODE_CBFS_GENERATE or
CPU_MICROCODE_CBFS_EXTERNAL is selected, however, the makefile checked that
CPU_MICROCODE_IN_CBFS was selected instead. The end result was that on
hasswell, the UPDATE-FIT step was always run, even when no microcode was
included, generating a build error.

Instead, introduce a new variable which tells if a microcode update is
added in CBFS during the build.
