[C/linux-azure][SRU][PATCH 1/1] UBUNTU: [Config]: disable CONFIG_SECURITY_SELINUX_DISABLE

[Po-Hsu Lin]

BugLink: https://bugs.launchpad.net/bugs/1813866

This option allows disabling selinux after boot and it will conflict
with read-only LSM structures. Since Ubuntu is primarily using AppArmor
for its LSM, it makes sense to drop this feature in favor of the
protections offered by __ro_after_init markings on the LSM structures.
(LP: #1680315)

Disable it to match the requirement in the kernel-security test suite.
