RFC: fix hard-coded section index in hppa-tdep.c

[Tom Tromey]

hppa-tdep.c passes 0 as the section index argument to ANOFFSET.  This
works ok since this is often the index of the text section.  However,
there's not really any requirement that this be true (it is true for SOM
due to how somread.c is currently written, but I doubt it is guaranteed
for other formats on HPPA).

This patch fixes the problem in the obvious way.

I built and tested this on HPUX as part of a much larger patch series.
However, I thought it was an obvious fix on its own.

In the absence of comments I plan to check it in after a few days.

	* hppa-tdep.c (read_unwind_info): Use SECT_OFF_TEXT, not "0".
