[SRU][Xenial linux-kvm][PATCH] UBUNTU: [Config]: enable KEXEC and KEXEC_FILE

[Connor Kuehl]

BugLink: https://bugs.launchpad.net/bugs/1799791

The enablement of these options could allow for some creative
applications of linux-kvm.

Set CONFIG_CRYPTO_SHA256=y instead of 'm' because KEXEC_FILE depends
on it being 'y' otherwise it precludes KEXEC_FILE. This also makes it
more consistent with Bionic as Bionic has it set to 'y' as well.

Finally, remove "sha256_generic" from the modules list as it is now
"built-in" after being set ='y'
