st/egl: Flush resources before presentation (android - bug 77966)

[olv: Use the real name provided by the patch author.  Ideally this could be
moved to somewhere higher level so that we would not need to create a pipe
context to flush resources.  Plus, it is not clear if flushing resources for
another context is valid.]
