perf event x86: Add retire_lat when synthesizing PERF_SAMPLE_WEIGHT_STRUCT
In arch_perf_synthesize_sample_weight(), the retire_lat was mistakenly
missed, add it.
perf test -v "x86 sample parsing"
74: x86 Sample parsing :
--- start ---
test child forked, pid 72526
Samples differ at 'retire_lat'
parsing failed for sample_type 0x1000000
test child finished with -1
---- end ----
x86 Sample parsing: FAILED!
