[committed][testsuite] Fix partial unit grepping in pr24468.sh

[Tom de Vries <tdevries@suse.de>]

Hi,

I'm running into:
...
FAIL: src/testsuite/dwz.tests/pr24468.sh
...

In more detail, we find the following offsets for partial units:
...
+ offsets='b
6b
da'
...
and then fail to find an import for the one at 6b:
...
++ grep -c 'DW_AT_import.*0x6b' READELF
++ true
+ imports=0
+ '[' 0 -gt 0 ']'
...

But there's actually no partial unit at 6b, the grep matches on a
DW_AT_import:
...
  <6b>  DW_AT_import  : <0xb>  [Abbrev Number: 17 (DW_TAG_partial_unit)]
...

Fix this by filtering out the DW_AT_import lines when grepping for partial
units.

Committed to trunk.

Thanks,
- Tom
