NOMMU: do not hide startup syscalls unless in -D mode

On NOMMU systems in "strace PROG" case, we have no way to attach to
the tracee before it calls execve unless in -D mode.  That is, the
first execve call is very likely to be missed, and setting
hide_log_until_execve just results to empty log.

* strace.c (init) [NOMMU_SYSTEM]: Do not set hide_log_until_execve
unless in -D mode.
