oeqa: add runtime 'maturin develop' test case

Similar to the sdk test case, build the "guessing-game" example from
https://maturin.rs/tutorial

This test case:
* creates a python3 venv
* echoes "nameserver 8.8.8.8" to /etc/resolv.conf as we need to have
  functional DNS to fetch the crates on target
* fetches crates, builds guessing-game crate and wheel

Put the following in your local.conf:

EXTRA_IMAGE_FEATURES += "tools-sdk"
SDK_INCLUDE_TOOLCHAIN = '1'
SDK_TOOLCHAIN_LANGS += 'rust'

IMAGE_INSTALL:append = " python3-maturin"

IMAGE_CLASSES += "testimage"
TEST_QEMUPARAMS ?= "-m 8192 -smp 4"
IMAGE_ROOTFS_EXTRA_SPACE = "10000000"
NOHDD="1"
NOISO="1"

TEST_SUITES = "ping ssh python maturin"

Test with:

bitbake core-image-full-cmdline
bitbake -c testimage core-image-full-cmdline
