fix(toolchains): use posix-compatible exec -a alternative (#3010)

The `exec -a` command doesn't work in dash, the default shell for
Ubuntu/debian.

To work around, use `sh -c`, which is posix and dash compatible. This
allows changing
the argv0 while invoking a different command. Also adds a test to verify
the the
runtime_env toolchain works with bootstrap script.
