pari-galpol: several improvements

- fix license
- change homepage and use https for downloads
- rename distfiles to include version in name
- compress files (installed-size: 80M -> 73M)
- drop depends on pari so pari can checkdepends on this (cf #29159, #32614)
- skip slow post-install hooks since pkg contains 14681 data files
- split a small subset as pari-galpol-small (12M vs 73M)
- add update file
- change of maintainer agreed by motorto
