[SRU][B:linux-kvm][PATCH v3 1/1] UBUNTU: [Config] kvm: Add support for modifying LDT

[Roxana Nicolescu]

BugLink: https://bugs.launchpad.net/bugs/2009442

Enables CONFIG_MODIFY_LDT_SYSCALL, adding support for modifying
the local descriptor table. This allows glibs autopkgtests to run
properly.

Config matches main kernel as well as newer versions of linux-kvm.
