Missing function fcntl64

We are missing fcntl64(), which should probably be a trivial alias to fcntl().
Needed by the newest versions of Fedora's openjdk, and causes a failure of Jenkins tests, eg., http://jenkins.cloudius-systems.com:8080/job/osv-build/1426/consoleFull

Can be reproduced by:
```
scripts/build -j4 image=openjdk8-fedora,tests
scripts/test.py --name 'java.*'
```
