BUILD: init: avoid a build warning on FreeBSD with USE_PROCCTL

It was brought by a variable declared after some statements in commit
21185970c ("MINOR: proc: setting the process to produce a core dump on
FreeBSD."). It's worth noting that some versions of clang seem to ignore
-Wdeclaration-after-statement by default. No backport is needed.
