cargo: Fix handling of relative sysroots (#1371)

Currently, `cc_toolchain.sysroot` is appended as an argument to "CC" and
"CXX". This argument, however, will typically be overridden by any
--sysroot flag already present in "CFLAGS" and "CXXFLAGS". When sysroot
is relative, this fails because cargo_build_script_runner is not
executed from the execroot.

Do not append `--sysroot` to "CC" and "CXX". Instead, modify any
--sysroot arguments with relative paths to be absolute.
