[commit] Fix warning from separate debug files

[Daniel Jacobowitz]

My recent patch enabling find_lowest_section unconditionally caused a
warning:

warning: no loadable sections found in added symbol-file .../libgcc_s.so.1.debug

This did not show up when I tested on x86_64, because the lowest
section in the debug files on my desktop is .note.gnu.build-id, which
is loadable in both regular and separate debuginfo files.  The ARM
tools I'm testing do not use build-id yet.

As with another recently fixed location in symfile.c, the SEC_LOAD
check should be SEC_LOAD | SEC_ALLOC.  The warning goes away, and now
the offsets are correct.

Also tested on x86_64-linux.  Checked in.
