[OpenJDK 2D-Dev] RFR: 7175487: Cannot customize font configuration on Linux

[Phil Race]

https://bugs.openjdk.java.net/browse/JDK-7175487
http://cr.openjdk.java.net/~prr/7175487/

As I note in the bug eval the probable issue here is that the file was 
found but rejected.
I've made the code more forgiving by removing the test that the file 
have references to font files.
The XLFD pattern for locating the files will work if they are missing (I 
did some manual testing).

Also the reference to OpenSolaris here is obsolete. There's more clean 
up that could be done
around that but for this fix I wanted to keep it about this Linux issue 
except for cleaning up
the overall if (..) logic
