gccrs: Fix infinite loop with missing comma

A missing comma between inline assembly templates did not throw an error
and looped indefinitely.

gcc/rust/ChangeLog:

* expand/rust-macro-builtins-asm.cc (parse_format_strings): Emit an
error when expecting a comma.

gcc/testsuite/ChangeLog:

* rust/compile/issue-4006.rs: New test.
