runtime(script.vim): make strace ft check less strict (#13482)

Strace output, depending on parameters (-ttf this time), can dump both
times and pid:
  1038  07:14:20.959262 execve("./e.py", ["./e.py"], 0x7ffca1422840 /* 51 vars */) = 0 <0.000150>

So loose the regexp matching this, so that the above is matched too.

Fixes #13481.
