rust-common: Hack around LD_LIBRARY_PATH issues on centos7
When building cargo-native on centos7 with buildtools tarball installed, we see failures: /bin/sh: /lib64/ version `GLIBC_2.33' not found (required by /home/pokybuild/yocto-worker/reproducible-centos/build/build-st/tmp/work/x86_64-linux/cargo-native/1.54.0-r0/recipe-sysroot-native/usr/lib/ We also see this for libstd-rs once cargo-native is fixed. The reason for this is that the wrapper script cargo-native/1.54.0-r0/wrapper/target-rust-ccld has /bin/sh as it's interpreter and cargo calls this with LD_LIBRARY_PATH set to include the recipe-sysroot-native. The host /bin/sh links to libtinfo from the host but it finds the version in the sysroot which needs a newer libc. This results in the above error since the loader is an older libc and the two are incompatible. Our ccld wrapper calls gcc/ld which don't need the LD_LIBRARY_PATH variable set. We can't patch this out the source since we're using a prebuilt binary to generate a new cargo binary so this is impossible to bootstrap. Instead, put a binary wrapper into place which removes LD_LIBRARY_PATH from the environment before calling the original wrapper (left in shell as it is simpler to maintain).
