The Linux kernel uses CONFIG_* as a way to determine if a feature
is available. Using CONFIG_* in an UAPI is considered an error
and in the most recent kernels will break a build. While we don't
have any CONFIG_* in our UAPI headers we do have CONFIG_T_*
which is used for config logs. This naming confuses the Linux
kernel build system so just rename these variables to MGS_CFG_T_*
instead.
