[Remarks] Warn if a remark file is not found when processing static archives

Static archives contain object files which contain sections pointing to
external remark files.

When static archives are shipped without the remark files, dsymutil
shouldn't generate an error.

Instead, generate a warning to inform the user that remarks for that
library won't be available in the .dSYM.
