Some EWS console logs doesn't go to log file
https://bugs.webkit.org/show_bug.cgi?id=160585
rdar://problem/24464570

Reviewed by Daniel Bates.

* Scripts/webkitpy/common/system/logutils.py:
(FileSystemHandler._open): Ensure that we open logfile in append mode in order to avoid
any possible overwriting.
* Scripts/webkitpy/common/system/filesystem.py:
(FileSystem.open_text_file_for_writing): Add should_append parameter to append to file.
* Scripts/webkitpy/common/system/filesystem_mock.py:
(MockFileSystem.open_text_file_for_writing): Same.
* Scripts/webkitpy/common/system/filesystem_unittest.py:
(RealFileSystemTest.test_read_and_write_text_file): Removed unused variable 'hex_equivalent'.
(RealFileSystemTest.test_append_to_text_file): Added new unit test for testing append functionality.
* Scripts/webkitpy/tool/commands/queues.py:
(AbstractQueue.begin_work_queue): Configure the logger for overall webkitpy to log to file.
This will ensure that all the sub-modules inside webkitpy will log to file.
