…S#457

This patch checks if the section header table is placed right after the
program header table such that it would overlap when we add a new entry
in the program header table.
If that is the case, move the section header table to the end of the file.

Moreover, there is no need to add a new PT_LOAD segment everytime.
Check if the last segment is already a PT_LOAD with the same characteristics
and adjacent. Extend it in this case.
