git_command: fix input passing

After reworking this function to use subprocess for output capturing
in commit c87c1863b1df392042c8859b81475a65315c8a9d ("git_command:
switch process capturing over to subprocess"), passing input via
stdin write no longer works.  We have to pass it via communicate(),
and we have to pass it a string instead of bytes (since we always
use encoding='utf-8' now).  This is fine since the only user of the
input= setting today is already passing in a string.
