kprobes: Fix Kconfig dependency
Fix Kconfig dependency among Kprobes, optprobe and kallsyms.
Kprobes uses kallsyms_lookup for finding target function and
checking instruction boundary, thus CONFIG_KPROBES should select
CONFIG_KALLSYMS.
Optprobe is an optional feature which is supported on x86 arch,
and it also uses kallsyms_lookup for checking instructions in
the target function. Since KALLSYMS_ALL just adds symbols of
kernel variables, it doesn't need to select KALLSYMS_ALL.
