zephyr: Build a script to call gcov
In chroot, you can always use llvm-cov to parse the coverage files, but
in zephyr sdk, you have to use the right gcov binary for each toolchain.
Use cmake to build a gcov shell script, and call it from zmake coverage.
BUG=None
TEST=zmake coverage in chroot and gitlab
BRANCH=None
