reason: since isula-build client file mode is too large(0551), we decided to remove other's permission(0550) on it. Beside, we change the public key(isula-build.pub) file mode to 0400(from 0444), so only the owner of the public key can read the key. After this commit, if the non-root user want to use command login, logout, build with args(http_proxy, https_proxy, etc...), they need use sudo to temporarily obtain root permission.
