Remove FHS from C source

The meaning of it is described at
https://www.jsoftware.com/help/user/lib_sysenv.htm#FHS. I guess this has
once been a compile option, but is now set runtime in stdlib.ijs.
This also resulted in jdllver no longer being referenced, and a
possiblity to combine two string append statements.
