cmd/internal/objfile: only consider executable segments for load address

Reportedly on some new Fedora systems the linker is producing extra
load segments, basically making the dynamic section non-executable.
We were assuming that the first load segment could be used to
determine the program's load offset, but that is no longer true.
Use the first executable load segment instead.

Fixes #26369
