This patch fixes two compile warnings introduced by commit
64b73291 ("util: create a copy of program_name"):
1. ../lib/util.c:457:5: error: passing argument 1 of 'free'
discards 'const' qualifier from pointer target type; And
2. ../lib/util.c:463:5: error: ISO C90 forbids mixed declarations
and code [-Werror=declaration-after-statement] (affected only
branch-2.3 that is C90 compliant and not the master)
