SETools patch for libselinux-2.3

[Sven Vermeulen <sven.vermeulen@siphos.be>]

In libselinux-2.3, the interface of the lsetfilecon_raw function has been
changed:

-extern int lsetfilecon_raw(const char *path, security_context_t con);
+extern int lsetfilecon_raw(const char *path, const char * con);

The call to lsetfilecon_raw in setools' secmds/replcon.cc needs to be
updated accordingly, as it otherwise fails during build:

replcon.cc: In function ‘int replcon_lsetfilecon(const char*, security_context_t)’:
replcon.cc:73:25: warning: NULL used in arithmetic [-Wpointer-arith]
replcon.cc:73:25: error: invalid operands of types ‘<unresolved overloaded function type>’ and ‘long int’ to binary ‘operator!=’

The below patch fixes this (but makes the setools version depend on
libselinux-2.3 now).

With thanks to Arfrever Frehtes Taifersar Arahesis for the patch (I worked
around it first by just calling lsetfilecon_raw directly). Something about
weakly linked functions...
