[PATCH] multipathd: Fix for 'Read environment variables from systemd'

[Ondřej Svoboda <ondrej@xxxxxxxxxxxxxx>]

The revision 'multipathd: Read environment variables from systemd' introduced a compilation error in multipathd/main.c:

main.c: In function ‘child’:
main.c:1651:2: error: ‘envp’ undeclared (first use in this function)
  envp = getenv("LimitNOFILE");
  ^

This patch fixes it by declaring char *envp for this (second) case.
