uml: network formatting

Style and other non-functional changes in the UML networking code, including
	include tidying
	style violations
	copyright updates
	printks getting severities
	userspace code calling libc directly rather than using the os_*
wrappers

There's also a exit path cleanup in the pcap driver.
