build: go faster, drop -fno-omit-frame-pointer

This flag was added back in 2013 to support postmortem debugging on
Linux but it has a pretty bad impact on performance (up to 10%) and
I don't think it's actually necessary to get meaningful stack traces.
Maybe with mdb but gdb and lldb seem to manage just fine.

Even if the flag is necessary for postmortem debugging, I don't think
it's appropriate to make performance for all users suffer for the
benefit of a fringe group.
