[PATCH -next,-tip ] kprobes: Fix Kconfig dependency

[Masami Hiramatsu]

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.
