Install of the alsalisp binary has been disabled since 2006 (in commit8d382ccd), and building of it was disabled by default in 2018 (in commit32ceab21), so it is reasonable to assume that nobody is using it. Use within the alsa-lib project is limited to an aliases file that looks like it is intended as an example, plus some very small .alisp files associated with the SiS SI7018 PCI sound card which has not been manufactured in years. These too have not been installed since 2018 when commit32ceab21disabled building of the alsalisp binary. In preparing this change, I searched the Github issue tracker for "lisp", "alisp" and "alsalisp", and found no complaints about the above changes. I also did a Github code search for projects that might be including the `alisp.h` header and found none. Therefore I think this code can be safely deleted and nobody is likely to object.
