Fix 'clone' failure at DOS root directory.

Cloning via relative path fails for a project residing immediately under
the root directory of a DOS drive.  For instance, for project c:/foo,
issuing "cd c:/" followed by "git clone foo bar" fails with error
"Unable to find remote helper for 'c'".  The problem is caused by
make_nonrelative_path() incorrectly returning c://foo rather than
c:/foo for input "foo".  The bogus path c://foo is misinterpreted by
transport_get() as a URL with unrecognized protocol "c", hence the
missing remote helper error.  Fix make_nonrelative_path() to return
c:/foo rather than c://foo (and /foo rather than //foo on Unix).
