Summary [WTF] Open files with O_CLOEXEC by default to avoid file handles leak

FileSystemPOSIX opens files without the O_CLOEXEC file in openFile() and openTemporaryFile(). This can cause file handles to be leaked to subprocess. For example, if the UIProcess opens content rules files from the ContentRuleListStore class between the NetworkProcess is spawned, the content rules file handles are leaked to the NetworkProcess. It does not seem useful to open files without O_CLOEXEC.
