script packages should cd into the SPKG directory

[mkoeppe]

This simplifies several spkg-install scripts and make script packages a bit more similar to normal packages.

This is a step towards #29386 (Install script packages via sage-spkg).

Depends on #29345

LGTM but is there some documentation that says what the initial working directory of spkg-install should be? It shouldn't be an implementation detail.
