[Skiboot] [PATCH] Makefile: Use '--ignore-errors unused' with lcov

[Reza Arbab]

We are a bit overzealous in specifying arguments to 'lcov -r', listing
files (via wildcard) that are not actually in the tracefile.

This is harmless, but will cause newer lcov to generate an error message
of type 'unused'. Reduce this error to a warning.
