Move main executable handling out of procmaps parser loop.
If the mapping for the main executable needed to be merged (for
example, if it was linked with lld and therefore contains an r mapping
followed by an r/x mapping), we would never reach the code that makes
it the first module. Handle that situation by moving that code into
a separate loop.
This fixes an issue where breakpad_unittests fails on Android devices
when linked with lld. It appears that the glibc dynamic loader
happens to always load executables (or at least the executables that
we create) at a lower address than DSOs, so we never hit this bug on
desktop Linux.
Testing: "make check" with both gold and lld as linker. Also
breakpad_unittests when patched into Chromium on Linux (lld) and
Android (gold and lld).
Bug: chromium:469376
