listout 05c5815fb9 Use fprintf instead of error
hidpp files were using the error function from error.h header file.
Unfortunately not every libc comes with this particular header file, so
with this patch we won't be requiring to be rely on error function and
use fprintf function.

Thanks to developer Yaroslav Chvanov <staticssleever668> for the
original suggestion

Closes: https://github.com/libratbag/libratbag/issues/1253
