Removing -debug-info-macros from option suggestions test

Summary:
https://reviews.llvm.org/D46776 added better support for prefixes for the
"did you mean ...?" command line option suggestions. One of the tests was
checking against the `-debug-info-macro` option, which was failing on the
PS4 build bot. Tests would succeed against the `--help` and `--version`
options.

From https://llvm.org/devmtg/2013-11/slides/Robinson-PS4Toolchain.pdf, it
looks like the PS4 SDK forces optimizations and *could be* disabling the
`-debug-info-macro` altogether.

This diff removes `-debug-info-macro` altogether.

Patch by Arnaud Coomans!

Test Plan: untested since we do not have access to a PS4 with the SDK.
