netfilter/exp: Add missing function prototypes

Add missing function prototypes for nfnl_exp_unset_flags(),
nfnl_exp_flags2str() and nfnl_exp_str2flags() to the public header.

This fixes the following GCC warnings when compiling with
-Wmissing-prototypes:

  netfilter/exp_obj.c:458:6: warning: no previous prototype for ‘nfnl_exp_unset_flags’ [-Wmissing-prototypes]
  netfilter/exp_obj.c:475:8: warning: no previous prototype for ‘nfnl_exp_flags2str’ [-Wmissing-prototypes]
  netfilter/exp_obj.c:481:5: warning: no previous prototype for ‘nfnl_exp_str2flags’ [-Wmissing-prototypes]
