[ovs-dev] [vlog 3/6] tests: Call vlog_init() consistently.

[Ben Pfaff]

I discovered that some of the Open vSwitch utilities don't call
vlog_init().  This leaves all of their log levels initially set to 0,
which is VLL_EMER, hence disabling logging entirely.  That wasn't
intentional, so this commit adds those calls, plus a few missing calls to
set_program_name().
