Solaris facts

Change "setup" module so that "ansible_processor" fact returns the CPU type for Solaris.
The fact now closely resembles that from a Linux system.

Example before...
```"ansible_processor": [ "The i386 processor operates at 2400 MHz," ]```
and after...
```"ansible_processor": [ "Intel(r) Core(tm) i5-3210M CPU @ 2.50GHz" ]```
