linker: small code-cleanup

This patch adds to make the linker a little bit easier to understand
by making all functions that acts on a sofino object with a soinfo_

This is to more easily distinguish functions that operate on global
state, and those that operate on individual libraries.

This should be purely stylistic, i.e. no feature/behaviour change.
