Allow including quadpack.f90 in user project #2

Currently the proposed preprocessor include for different precision does fail with:

❯ cat > app/my_quadpack.F90 <<EOF
module quadpack_single
use iso_fortran_env, only: wp => real32
#define MOD_INCLUDE=1
#include "quadpack.f90"
end module quadpack_single
EOF
❯ fpm build
 + gfortran -c app/my_quadpack.F90  -Wall -Wextra -Wimplicit-interface -fPIC -fmax-errors=1 -g -fcheck=bounds -fcheck=array-temps -fbacktrace -fcoarray=single -J build/gfortran_2A42023B310FA28D/quad-prec -I build/gfortran_2A42023B310FA28D/quad-prec  -o build/gfortran_2A42023B310FA28D/quad-prec/app_my_quadpack.F90.o
app/my_quadpack.F90:5:2:

    5 | end module quadpack_single
      |  1~~~~~~~~~~~~~
Fatal Error: quadpack.F90: No such file or directory
compilation terminated.

However, if this projects exports a library.include-dir = "src" fpm will find and include the source file correctly.

Thank you!! For some reason, the way I had it worked on my laptop, but not in the GitHub CI. I'm not really sure why...
