which does causes problems in Kokoro with the latest update.

Also removes the use of the hermetic flag in favor of not failing the
build if the submodule is not checked out.
This allows us to remove the tpm2 build from the build_environment
Makefile.

This CL adds a "tpm" Cargo cfg to crosvm which enables a TPM device
backed by libtpm2 simulator.
Tested by running the following inside cros_sdk:
LIBRARY_PATH=~/src/minijail LD_LIBRARY_PATH=~/src/minijail \
cargo run --release \
--features tpm \
-- \
run \
-r rootfs.ext4 \
--seccomp-policy-dir seccomp/x86_64/ \
-p init=/bin/bash \
-p panic=-1 \
--disable-sandbox \
vmlinux.bin
with a Linux image built from CL:1387655.
The TPM self test completes successfully with the following output:

This CL adds a tpm2-sys crate that builds libtpm2 from source (from a
git submodule) using the existing Makefile and then links the generated
static library as -ltpm2.
For production builds there is a flag `RUSTFLAGS='--cfg hermetic'` to
disallow building our own libtpm2. Instead it will expect to find
libtpm2 installed in the standard system location. Building from the
libtpm2 submodule is a convenience only intended for developer
environments.
The functions exposed by tpm2-sys are the ones that will be necessary to
initialize a TPM simulator in crosvm and execute TPM commands. Trunks
uses the same functions for its simulator mode here:
e4cf13c057/trunks/tpm_simulator_handle.cc
Tested by running:
fn main() {
unsafe {
tpm2_sys::TPM_Manufacture(1);
}
}
inside cros_sdk. Libtpm2 cannot be built outside of cros_sdk because it
requires openssl 1.0.2p, whereas dev machines come with openssl 1.1.0j.
I have not yet added any dependency on tpm2-sys from crosvm, but when it
does get added it will be behind a tpm feature flag so that crosvm can
continue to build outside of cros_sdk just without tpm support.
I published num_cpus version 1.9.0 to chromeos-localmirror.
