Verify sun.nio.{ch.PollSelectorImpl,fs.UnixFileStore}.

Integrate forgotten sun.nio.* fixes between OpenJDK 8u60 and 8u121-b13.

This applies upstream fixes that were backported to OpenJDK 8u72 but
were forgotten to apply when updating libcore from 8u60 to 8u121-b13.

1.) JDK-8130274 : java/nio/file/FileStore/Basic.java fails when two
    successive stores in an iteration are determined to be equal

    Change UnixFileStore.equals() to consider entry.name() from equals();
    hashCode() continues to not consider it.

2.) JDK-8138819 : (se) File descriptor leak when Selector.open fails

    Close file descriptors on exception path in PollSelectorImpl ctor.

After this CL, the files touched by this CL are exactly identical to
the versions in OpenJDK 8u121-b13. Constructing a regression test case
for these fixes is too complicated to be worthwhile; therefore
regression test coverage for these changes is omitted.
