tdf#128226: make OpenSymbol font an internal resource

OpenSymbol is crucial for Math; so it is not just some font that
could be used if present, but part of program resources. As such,
it must be available with other program resources, and not depend
on user preferences, like uninstallation of the font from system.

This patch puts it into program/resource/common/fonts, and adds
that path to the paths used for private fonts. This is in addition
to share/fonts/truetype, which is optional, and is usually absent
on most Linux and Windows installations (on Linux, it is usually
in a separate package installing it to system fonts; on Windows,
it is also installed to system by MSI).
