Bug 1063520 - Compute the list of B2G ELF files instead of hard-coding it g=gsvelto

We explicitely exclude those files because they are part of the update:
checking their SHA1 is useless and will stop the update process because
of the expected mismatch. We instead rely on file to identify the files
in the B2G folder that have a mimetype for shared library or executable.

Bug 1022928 - Use breakpad symbols when available.

Add a new option to profile.sh:
    -s <breakpad-symbol-path>

When this option is used, symbols are resolved using breakpad .sym
files.

This is useful for running profile.sh against nightly builds.
