lo-specfun.cc: Remove code duplication for airy and biry functions (bug #62321)
Co-author: Zoïs Moitier <zois.moitier@kit.edu>
lo-specfun.cc: The external Fortran library functions ZAIRY, CAIRY, ZBIRY, and
CBIRY can already scale or unscale their respective results depending on
whether an input parameter KODE is set to 1 or to 2. This changeset removes
the duplication of that scaling functionality in lo-specfun.cc, and calls the
library functions with the appropriate value of KODE.
