We can always pass to strace(1) the exact list of system calls we want.
So there's no essential need for new strace selectors.  The only thing
that stopped me from implementing --trace=open,execve,... argument for
/usr/share/buildreqs/strace_files is that actually I would have to deal
with stat/stat64 difference somehow.
