build: Remove disable sframe workaround This was to work around a linker problem when building with the gLinux standard GCC toolchain: https://yaqs.corp.google.com/eng/q/3916204231928840192 This flag isn't supported for some other toolchains (e.g. what we use in CI), so we can instead just move this to a .bazelrc for building locally.
