Changes to SkFontHost_linux

Changes to SkFontHost_linux

* Use SkOSPath::SkPathJoin() rather than append so that
  SK_FONT_FILE_PREFIX does not have to end in a '/'.

* Add another font to the default font list.

Motivation: Some tests fail when there are no default fonts.

File src/ports/SkFontHost_linux.cpp (right):

https://codereview.chromium.org/195733007/diff/20001/src/ports/SkFontHost_lin...
src/ports/SkFontHost_linux.cpp:364: load_directory_fonts(dirname);
Can we use SkOSPath::SkPathJoin here as well, and then remove
SK_FONT_FILE_DIR_SEPERATOR? That would make this handling consistent, and then
we'd just have the one SkPATH_SEPARATOR. (This file was written before that
existed).
