LibDebug: Use the first memory segment of a library as the ELF's base
When parsing the libraries of the debugee process, we previously
assumed that the region that's called `<library name>: .text` was also
the base of the ELF file.
However, since we started linking with `-z separate-code`, this is no
longer the case - our executables have a read-only segment before the
.text segment, and that segment is actually at the base of the ELF.
This broke inserting breakpoints with the debugger since they were
inserted at a wrong offset.
To fix that, we now use the address of the first segment in the memory
map for the ELF's base address (The memory map is sorted by address).
