Log message:
Update comment, replace librsvg with librsvg-c

Log message:
*: use LIBRSVG_TYPE instead of PLATFORM_SUPPORTS_RUST

Log message:
Include mk file earlier to enable rust conditional

Log message:
Add graphite2 to librsvg via pango and harfbuzz

librsvg with pango and harfbuzz with graphite2 is required for libreoffice.
librsvg-c has the problem on NetBSD and libreoffice uses internal static
harfbuzz library. Rust-based librsvg has no problem and libreoffice use
dynamic harfbuzz from fonts/harfbuzz.

Bump PKGREVISIONs.
