[oe] [meta-oe][PATCH] poppler-data: install CMap resources for CJK glyph support

[Joshua Lock]

CID-keyed fonts, as commonly used to support pictographic East
Asian character sets require Character Maps which unidirectionally
map character codes (i.e. Unicode encoding) to CID (the glyphs in
the font face).

Without a CMap poppler isn't able to correctly PDF files in
Chinese, Japanese or Korean without embedded fonts.

This change installs a copy of the Identity files from Adobe's
CMap Resources[1] based on a similar change in Fedora's
poppler-data[2][3].
