[Buildroot] [PATCH v2 3/7] tpm2-tools: always disable hardening options

[Peter Korsgaard <peter@korsgaard.com>]

Building with --enable-hardening (the default), forces -fstack-protector-all
/ FORTIFY_SOURCE=2.  These options are now controlled Buildroot wide with
the BR2_SSP_* / BR2_FORTIFY_SOURCE_* options.  Disable hardening so the
ssp/fortify settings in the toolchain wrapper / CFLAGS is used instead.
