Yet again, selinux has been adding const-correctness; this change
is ABI-compatible, but breaks API, which affects us when we try to
override things in our testsuite:
../../tests/securityselinuxhelper.c:307:24: error: conflicting types for 'selabel_open'
struct selabel_handle *selabel_open(unsigned int backend,
^~~~~~~~~~~~
In file included from ../../tests/securityselinuxhelper.c:32:0:
/usr/include/selinux/label.h:73:24: note: previous declaration of 'selabel_open' was here
The problem is a new 'const' prior to the second parameter.
Fix it the same way we did in commit 292d3f2d: check for the new
const at configure time.
