Linear response tests fail with libxc/5.1.2

Description

When linking the octopus to libxc/5.1.2, the following tests fail:

linear_response/01-casida.05-casida.inp
linear_response/01-casida.08-casida_restart.inp
linear_response/02-h2o_pol_lr.03_h2o_dyn_pol_cmplx.inp

with this message:

**************************** FATAL ERROR *****************************
*** Fatal Error (description follows)
*--------------------------------------------------------------------
* From node =    0

* Cannot calculate kernel derivative. This functional does not have Kxc available.

Apparently, the value of functl(ixc)%flags is set to 135 b(10000111) with libxc/5.1.2 but it is 143 b(10001111) with libxc/4.3.4. [the value of XC_FLAGS_HAVE_KXC is 8 b(1000)]

This happens when compiling with both the Intel and GNU compilers.
