dmd: set --sysroot=/ to avoid cc-wrapper value

Browse source 
After https://github.com/NixOS/nixpkgs/pull/210004 `dmd` started failing
build as:

    ld: warning: libm.so.6, needed by ./generated/linux/release/64/lib.so, not found (try using -rpath or -rpath-link)
    ld: /build/druntime/generated/linux/release/64/libdruntime.so: undefined reference to `log10@GLIBC_2.2.5'

This happens because --sysroot=/nix/store/does/not/exist removes not
just include headers by prefixing wrong path, but also removes RUNPATH
dependencies of linked libraries. It's an unintended effect.

Restore the build by reversing the effect with --sysroot=/.

# Workaround cc-wrapper's --sysroot= value for `staging-next`: it
# breaks library lookup via RUNPATH:
# ld: warning: libm.so.6, needed by ./generated/linux/release/64/lib.so, not found (try using -rpath or -rpath-link)
# ld: /build/druntime/generated/linux/release/64/libdruntime.so: undefined reference to `log10@GLIBC_2.2.5'
# TODO(trofi): remove the workaround once cc-wrapper is fixed.
