opensuse_sysconfig_get_string and opensuse_sysconfig_get_boolean to
our patch lightdm-sysconfig-support.patch so that the package
compiles with compilers which by default enforce C99 standard such
as GCC 14. [boo#1221704]
If the request is OK, please also forward it to Factory soon-ish so
that we can switch the default compiler.
