bhyve: uniform printf format string newlines

[vmaffione]

Summary

Some of the printf statements only use LF to get a newline. However, a CR character is also required for the serial console to print debug logs in a nice way.
Fix those code locations that only use LF, by adding a CR character.

[afedorov]

I welcome these changes. The current debug output looks like a mess.
Moreover, part of the files declares (W/D)PRINTF as

#define        WPRINTF(params) printf params

other as

#define WPRINTF(format, arg...) printf(format, ##arg)

So, in some places the call looks like WPRINTF(fmt, args), in other WPRINTF((fmt, args))

After applying the patch, there are still places without using CR. It would be nice to fix them too.
