sh: Switch yay to paru

Removed outdated `syu` symlink which just hooks into topgrade.
Replaced it with simple function that tries for topgrade, paru, yay,
pacman, in that order. Can still be invoked with simple `syu` command,
but *only* through interactive terminal use.

Switched git pre-commit hook to default to paru instead of yay when
compiling installed package lists for dotfile commits.
