intel: fix string truncation warnings
Fix -Wformat-truncated warnings to complete the intel directories' W=1
clean efforts. The W=1 recently got enhanced with a few new flags and
this brought up some new warnings.
Switch to using kasprintf() when possible so we always allocate the
right length strings.
summary of warnings:
