[PATCH] gitweb: Use single implementation of export_ok check.

GitWeb source contains a special function that implements the
export_ok check, but validate_project still uses a separate copy
of essentially the same code.

This patch makes it use the dedicated function, thus ensuring
that all checks are done through a single code path.

	For reference, here is the function:

	sub check_export_ok {
		my ($dir) = @_;
		return (check_head_link($dir) &&
			(!$export_ok || -e "$dir/$export_ok"));
	}
