The 3.3.2 fix for respecting testNow in createFromFormat
incorrectly applied testNow values when using the Unix timestamp
format 'U'. Since 'U' sets all date/time components from the
Unix timestamp value, testNow should not be applied.
This caused createFromFormat('U', '0') to return the current
test time instead of the Unix epoch (1970-01-01 00:00:00).
The fix adds 'U' to the list of format specifiers that should
skip the testNow application, similar to '!' and '|'.

Summary
The 3.3.2 fix for respecting testNow in createFromFormat (#494) incorrectly applied testNow values when using the Unix timestamp format 'U'. Since 'U' sets all date/time components from the Unix timestamp value, testNow should not be applied.
Problem
This broke CakePHP's test suite after 3.3.2 was released.
Fix
Add 'U' to the list of format specifiers that should skip the testNow application, similar to '!' and '|'.
Test
Added test cases for Unix timestamp format with testNow set.
