Subject: [PATCH] client: fix parsing of -v command option

The sources and sourcestats commands accept -v as an option, but the
glibc implementation of getopt() reorders the arguments and parses the
option as a command-line option of chronyc.

Add '+' to the getopt string to disable this feature. Other getopt()
implementations should consider it a new command-line option, which will
be handled as an error if present.
