Fix for -Wp,MD

[cwyang]

This fix ensures that icecc properly handles dependency arguments where the filename is embedded in the option itself, rather than trying to override it with its own dependency file specification.

When I build dpdk (from ceph), icecc emits following error.
We can see that this is caused by icecc correctly identifying -Wp,-MD,./.telemetry_legacy.o.d.tmp as a dependency-generating option but then incorrectly adding its own -MF option later:
