build.config: Enable hermetic toolchain on msm-kernel

Enable "mostly" hermetic toolchain on msm-kernel for targets which need
openssl.  For those targets, use DISABLE_HERMETIC_SYSROOT to work around
missing aosp/1843323. This change enables a hermetic PATH, but still
uses host's sysroot for system libraries.
