perf tools: Remove show_mask bitmask
As it was not being exposed via any command line and with --dsos/--comms
we can do this and even more, like asking for just kernel + some module:
[root@doppio linux-2.6-tip]# perf report --dsos \[kernel\],\[drm\]
--vmlinux /home/acme/git/build/tip-recvmmsg/vmlinux --modules | head -15
# Samples: 619669
