git-quiltimport: preserve standard input to be able to read user input

When run without --author and it fails to determine an author, git
quiltimport tries `read patch_author` to get user input, but standard
input has been redirected to the patch series file.  This commit lets
quiltimport read the series file through file descriptor 3 so that the
standard input is preserved.
