submodule.c: write "Fetching submodule <foo>" to stderr

Browse Source 
The "Pushing submodule <foo>" progress output correctly goes to
stderr, but "Fetching submodule <foo>" is going to stdout by
mistake.  Fix it to write to stderr.

Noticed while trying to implement a parallel submodule fetch.  When
this particular output line went to a different file descriptor, it
was buffered separately, resulting in wrongly interleaved output if
we copied it to the terminal naively.
