Subject: [PATCH] runtime: fix user symbol lookups when the first section isn't
 executable

The first section of a user binary may not be executable, which breaks
the current assumption that the executable section always starts at an
offset of zero. This can result in the executable section's VMA never
being added, which breaks lookups for symbols inside that section.

To fix this, remove the faulty assumption that the executable section
starts at an offset of zero, and store the offset of each VMA region
added so that symbol lookups into an offset section return the correct
result.
