perf/x86/intel: Make the CYCLE_ACTIVITY.* constraint on Broadwell more specific

The counter constraint for CYCLE_ACTIVITY.* on Broadwell covered
all CYCLE_ACTIVITY.* sub events, and forced them on counter 2.
But actually only one sub event (umask 8) needs to be on counter 2,
all others do not have any constraint.

Only force that subevent. This fixes groups with multiple
CYCLE_ACTIVITY.* events, for example:

	% perf stat -x, -e '{cpu/event=0xa3,umask=0x6,cmask=6/,\
	cpu/event=0xa2,umask=0x8/,\
	cpu/event=0xa3,umask=0x4,cmask=4/,cpu/event=0xb1,umask=0x1,cmask=1/}' true
	122150,,cpu/event=0xa3,umask=0x6,cmask=6/,846486,100.00
	16483,,cpu/event=0xa2,umask=0x8/,846486,100.00
	252280,,cpu/event=0xa3,umask=0x4,cmask=4/,846486,100.00
	233604,,cpu/event=0xb1,umask=0x1,cmask=1/,846486,100.00
	%

Without this patch the third result would be <unsupported>
