Revert an upstream commit to enable compiling without external glib2.

Edit the 'disable UI compilation' patch to match the original
upstream commit more closely.

The purpose of irqbalance is to distribute hardware interrupts across
processors/cores on a multiprocessor/-core system in order to increase
performance.

This initial implementation of the package uses external glib2,
which is a large dependency.
Only the cmd-line tool is compiled and installed.

Run-tested with ipq806x / R7800.
