LibELF: Split do_relocation into do_{direct,plt}_relocation

Browse source 
No functional changes intended. This is in preparation of a commit that
overhauls how IFUNCs are resolved.

This commit lets us move the implementation of PLT patching from
`DynamicObject` to `DynamicLoader` where all other relocation code
lives. For this, got[2] now stores the loader's address instead of the
object's.
