latest picard-1.119 doesn't include sam-119.jar. Fixed sanity check

why not include a version check instead, rather than making this less strict? something like this (needs testing!)

```python
jar_files = ['picard']
    if LooseVersion(self.version) < if LooseVersion('1.119'):
    jar_files.append('sam')
custom_paths = {
    'files': ["%s-%s.jar" % (x, self.version) for x in jar_files],
    'dirs': [],
}  
```
