recipetool: fix unbound variable when fixed SRCREV can't be found

If attempting to find a fixed SRCREV fails because the directory doesn't exit,
avoid failing with:

  Traceback (most recent call last):
    File "/home/vagrant/poky/scripts/recipetool", line 121, in <module>
      ret = main()
    File "/home/vagrant/poky/scripts/recipetool", line 110, in main
      ret = args.func(args)
    File "/home/vagrant/poky/scripts/lib/recipetool/create.py", line 707, in create_recipe
      srcrev = stdout.rstrip()
  UnboundLocalError: local variable 'stdout' referenced before assignment

Fixes: 000480c42797 ("recipetool / devtool: set a fixed SRCREV by default when fetching from git")
