Support inject delay running with the old version (4.x) of strace for test case.

Browse Source 
Only the newer version of strace can support `--detach-on` options
and set time duration with human readable string.

In the 4.x version of strace, using `-b` to replace `--detach-on`,
and injecting a delay with int usecs.
