tools headers x86 svm: Sync svm headers with the kernel sources

To pick the changes in:

827547bc3a2a2af6 ("KVM: SVM: Add architectural definitions/assets for Bus Lock Threshold")

That triggers:

CC /tmp/build/perf-tools/arch/x86/util/kvm-stat.o
LD /tmp/build/perf-tools/arch/x86/util/perf-util-in.o
LD /tmp/build/perf-tools/arch/x86/perf-util-in.o

LD /tmp/build/perf-tools/perf-util-in.o
AR /tmp/build/perf-tools/libperf-util.a
LINK /tmp/build/perf-tools/perf

The SVM_EXIT_BUS_LOCK exit reason was added to SVM_EXIT_REASONS, used in
kvm-stat.c.

This addresses this perf build warning:

Warning: Kernel ABI header differences:
