ippusb_manager: handle EINTR and log errnos

Add HANDLE_EINTR wrappers around some of the syscalls in socket_manager.
When appropriate, replace LOG statements with PLOG so that errno will be
printed as well.

The purpose of this is to minimize reporting spurious failures and
closing ippusb_manager when we should have just retried a syscall.

BUG=None
TEST=run printer.PrintIPPUSB
