http.c: remove unnecessary casts to long

When parsing 'http.lowSpeedLimit' and 'http.lowSpeedTime', we explicitly
cast the result of 'git_config_int()' to a long before assignment. This
cast has been in place since all the way back in 58e60dd (Add support
for pushing to a remote repository using HTTP/DAV, 2005-11-02).

But that cast has always been unnecessary, since long is guaranteed to
be at least as wide as int. Let's drop the cast accordingly.
