Backport move to Ubuntu Bionic and GCC7 in Gitian builds (#2225)

* Add stdin, stdout, stderr to ignored export list

* Merge bitcoin#13171: Change gitian-descriptors to use bionic instead

c1afe32 Change gitian-descriptors to use bionic instead (Chun Kuan Lee)

Pull request description:

  I have tested this with Ubuntu Bionic host with lxc 3.0.0, the gitian-build for Windows and MacOSX work fine, but there is an issue about it for Linux. Failed at check-symbol:
  ```
  test/test_bitcoin: symbol __divmoddi4 from unsupported version GCC_7.0.0
  test/test_bitcoin: symbol log2f from unsupported version GLIBC_2.27
  qt/bitcoin-qt: symbol __divmoddi4 from unsupported version GCC_7.0.0
  qt/bitcoin-qt: symbol log2f from unsupported version GLIBC_2.27
  ```
  I think this should be fixed in `./configure --enable-glibc-back-compat`

  Should not be merged before bitcoin#13177 devrandom/gitian-builder#178

  Close bitcoin#12511

* Use IN6ADDR_ANY_INIT instead of in6addr_any

This is the same fix as bitcoin@fc6a9f2
Couldn't backport the original commit as we are missing some refactorings.
