Update rust to at least 1.56 so we can update clamav

This may only work on 3.0-current

Created rust166-bin and rust167 ports for 3.0 and higher. Suggest we add a clamav port that's newer also once the rust ports are stable.

The rust167 port is failing in the do-install stage because the names of the tarballs don't match the component names. adding -dev somewhere in the string. I tried to get clever but some names are not following the pattern.

do-install:
    -${RM} -r ${WRKDIR}/_extractdist
.for _c in ${_COMPONENTS}
#cargo-1.67.1-dev-i686-unknown-freebsd.tar.xz
    -${MV} ${WRKDIR}/_build/dist/${_c:S|i686|dev-i686|}.tar.xz ${WRKDIR}/_build/dist/${_c}.tar.xz
    ${MKDIR} ${WRKDIR}/_extractdist
    ${TAR} xf ${WRKDIR}/_build/dist/${_c}.tar.xz -C ${WRKDIR}/_extractdist
    -${MV} ${WRKDIR}/_extractdist/${_c:S|i686|dev-i686|} ${WRKDIR}/_extractdist/${_c}
    cd ${WRKDIR}/_extractdist/${_c} && \
            ${SH} install.sh \
            --docdir="${DOCSDIR}" \
            --mandir="${PREFIX}/share/man" \
            --prefix="${PREFIX}"
    -${RM} -r ${WRKDIR}/_extractdist
.endfor

It's also creating tar.xz and tar.gz files in there which is weird. FreeBSD 13.1 is also doing the same.

Created a possible workaround ce9cba7

This is building on a 3.0 i386 node.
