[Thadeu Lima de Souza Cascardo]

BugLink: https://bugs.launchpad.net/bugs/1866149

[Impact]
systemd-systemctl will fail to set kernel.pid_max, leading to a degraded boot.

[Fix]
Set CONFIG_BASE_FULL=y, CONFIG_BASE_SMALL=0.

[Test case]
Write 419304 to /proc/sys/kernel/pid_max.

[Potential regression]
Boot time may be affected.
