Stop pointing to "gn help toolchain" in that very help message.

toolchain_args became a variable in commit 22227896 ("Update GN
toolchain_args to be a variable"), but the help message was copy-pasted
from when it was a separate function and referenced the toolchain
function's help message.

Remove that reference now that it is pointing to itself.
