WASI: Switch to crt1-command.o to enable support for new-style commands

This switches Rust's WASI target to use crt1-command.o instead of
crt1.o, which enables support for new-style commands. By default,
new-style commands work the same way as old-style commands, so nothing
immediately changes here, but this will be needed by later changes to
enable support for typed arguments.

See here for more information on new-style commands:

 - https://reviews.llvm.org/D81689
