Some su implementations require -c before command

[BurntBrunch]

Cyanogen running on m7:

: fb-adb shell -r
fb-adb shell: trouble re-execing adb stub as root: Unknown id: stub

shell@m7:/ $ su whoami
Unknown id: whoami
1|shell@m7:/ $ su -c whoami
root

Can you reproduce after b230619?

I get this off of master:

$  fb-adb -r shell echo 'hello'
fb-adb shell: trouble re-execing adb stub as root: fb-adb stub: execvpe("su"): Invalid argument

$  fb-adb -r shell
fb-adb shell: trouble re-execing adb stub as root: fb-adb stub: execvpe("su"): Invalid argument

I restored the function from https://github.com/facebook/fb-adb/blob/1.4.4/cmd_stub.c and it seems to be working for both shell and ctar
