Source/WebKit/chromium:

Remove all fifo-related code together with the io_stream_forwarder_android
target defined in WebKitUnitTests.gyp.

* WebKitUnitTests.gyp:
* tests/ForwardIOStreamsAndroid.cpp: Removed.
* tests/ForwardIOStreamsAndroid.h: Removed.

Tools:

We switched Chromium to using FIFOs in order to achieve better consistency,
which was done by Marcus in r157541. Remove all custom WebKit code in
favor of Chromium's implementation.

Remove more FIFO code in the test runner itself, including the code in
DumpRenderTree that invoked it. We can now switch to Chromium's brand
new FIFO-creating code, which is being set-up for all test targets build
for Android, including DumpRenderTree, TestWebKitAPI and webkit_unit_tests.

This also changes the ChromiumAndroidDriver._remove_all_pipes method to
delete the files individually. "rm" would fail if one of the earlier files
does not exist, and the "-f" argument doesn't seem to be reliable.
