[committed] Remove leading whitespace in gnu-debugaltlink-name.sh output

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

Hi,

Currently, gnu-debugaltlink-name.sh prints leading whitespace:
...
$ echo \""$(./testsuite/scripts/gnu-debugaltlink-name.sh 1)"\"
"  3"
...

Fix this by using sed to extract the name from the readelf output.

With that fixed, we add quotes to gnu-debugaltlink-name.sh calls to prevent
"unary operator expected" errors.

Thanks,
- Tom
