Use get_frame_address_in_block in print_frame

Use get_frame_address_in_block in print_frame

The author of 'mold' pointed out that with a certain shared library,
gdb would fail to find the shared library's name in 'bt'.

The function in question appeared at the end of the .so's .text
segment and ended with a call to 'abort'.

This turned out to be a classic case of calling get_frame_pc when
get_frame_address_in_block is needed -- the former will be off-by-one
for purposes of finding the enclosing function or shared library.

The included test fails without the patch on my system.  However, I
imagine it can't be assumed to reliably fail.  Nevertheless it seemed
worth doing.

Regression tested on x86-64 Fedora 38.
