kconfig: Use PATH_MAX instead of 128 for path buffer sizes.
This prevents the buffers being overflowed when using a config file with a long name. PATH_MAX is used elsewhere in the same file, so use it here as well. Signed-off-by: Will Newton <will.newton@imgtec.com> Acked-by: WANG Cong <xiyou.wangcong@gmail.com> Signed-off-by: Michal Marek <mmarek@suse.cz>
