check_icmp: Populate progname before np_extra_opts call (#2226)HEADmastercoverity/master

Within np_extra_opts, the ini parser expects a valid progname as the
default section to select a configuration section in the ini file.
However, within the check_icmp codebase, the progname is being populated
directly after the np_extra_opts call, being a null pointer before.

$ ./check_icmp --extra-opts=@foo.ini
Segmentation fault (core dumped)

The progname variable is set within the process_arguments function,
requiring the already enriched arguments from np_extra_opts. Thus, I
moved the progname detection out of this function, directly before the
np_extra_opts call. This pattern does already exists in check_tcp.

I briefly looked for similar issues in other plugins, but found none.
