[libvirt] [PATCH 2/2] virSecuritySELinuxSetFileconHelper: Fix build with broken selinux.h

[Michal Privoznik]

There are still some systems out there that have broken
setfilecon*() prototypes. Instead of taking 'const char *tcon' it
is taking 'char *tcon'. The function should just set the context,
not modify it.

We had been bitten with this problem before which resulted in
292d3f2d and subsequently b109c09765. However, with one my latest
commits (4674fc6afd6d) I've changed the type of @tcon variable to
'const char *' which results in build failure on the systems from
above.
