SubjectRe: file caps: permit unsafe signaling when CONFIG_FS_CAPS=n

Uh, never mind. It does the right thing. CONFIG_SECURITY=n means we
use capabilities, but CONFIG_SECURITY=y and CONFIG_SECURITY_CAPABILITIES=n
means we use dummy. The following patch fixes the Kconfig accordingly.

From: Serge E. Hallyn <serue@us.ibm.com>
Subject: [PATCH 1/1] file caps: don't show FILE_CAPABILITIES option when not relevant

FILE_CAPABILITIES are relevant when CONFIG_SECURITY=n, but not when
CONFIG_SECURITY=y && CONFIG_SECURITY_CAPABILITIES=n. So make
CONFIG_SECURITY_FS_CAPABILITIES depend on the right conditions.
