[PATCH 1/2] chcon: use security_check_context() for context validation |

It seems context_new() and _free() are used for checking validity of
a specified context. The libselinux provides security_check_context
for this purpose so use it.
Note that context_new() can fail for a valid context - e.g. ENOMEM.
* src/chcon.c (main): Use security_check_context().
