Add LibXC alias xc names in param.f90

Some functionals defined in get_method_id inside param.f90 have
an alias in LibXC. In particular, these are:
- b1b95 == b88b95 as in LibXC this is HYB_MGGA_XC_B88B95
- bhlyp == bhandhlyp as in LibXC this is HYB_GGA_XC_BHANDHLYP
(assuming that bhlyp refers to the implementation with Becke 88
exchange instead of LDA exchage - see
J. Chem. Phys. 159, 114116 (2023), DOI: 10.1063/5.0167763)
- pbe0 == pbeh as in LibXC this is HYB_GGA_XC_PBEH

These aliases have been added to be compatible with codes that use
LibXC with automatic D3 parameter recognition
