Enable CONFIG_FTRACE_SYSCALLS for kernel-mshv (helps with eBPF)

[Jongy]

mshv kernels (x86_64) have CONFIG_FTRACE_SYSCALLS disabled:

azurelinux/SPECS/kernel-mshv/config

Line 7394 in 950c61a

# CONFIG_FTRACE_SYSCALLS is not set

it is enabled in aarch64 however:

azurelinux/SPECS/kernel-mshv/config_aarch64

Line 11240 in 950c61a

CONFIG_FTRACE_SYSCALLS=y

it is very helpful for eBPF tracing, and was re-enabled for the regular "kernel" in the past for similar reasons - #3210

can we enable it for mshv as well?
