irmp: silence "illegal character encoding" compiler warning

Replace non-ASCII characters in the FDC keyboard map with their
respective number values, since the character presentation is
non-portable and results in compiler warnings.

A similar change was done in IRMP version 3.2.0 (SVN r192 as of
2020-06-22) which the sigrok project has not caught up with yet.
