tdf#159529 Use macOS font table memory directly instead of copyingHEADmaster

Per Apple's documentation, the CFDataRef returned by the
CTFontCopyTable() function is "A retained reference to the
font table data as a CFDataRef object. The table data is not
actually copied; however, the data reference must be released."

So, instead of making a copy of the CFDataRef's data, just use
the CFDataRef's data pointer for the HarfBuzz blob and release
the CFDataRef in the blob's destroy function.
