Proposing SELinux support in strace

[Renaud Métrich]

Hi Dmitry,

Sorry for the delay, I was busy this week.

I pushed the new code with updated test suite.

Still I have an issue regarding 1 test: test_personality_64

I don't understand what is supposed to be checked here, the strace runs 
on "getcwd" but fails because now some tests (including "execveat") use 
getcwd() internally.

Renaud.
