[committed][gdb/testsuite] Fix ls_host return in index-cache.exp

[Tom de Vries]

Hi,

When adding a debug print here in index-cache.exp:
...
 proc_with_prefix test_cache_disabled { cache_dir } {
     lassign [ls_host $cache_dir] ret files_before
+    puts "before: '$files_before'"
+    exit
...
we have:
...
files_before: ''
...

When further adding:
...
 proc_with_prefix test_cache_disabled { cache_dir } {
+    exec touch $cache_dir/foo.1 $cache_dir/foo.2 $cache_dir/foo.3
...
we have:
...
files_before: 'foo.1'
...
while we're expecting file_before to contain foo.[123].

Fix this by making the return statement in ls_host return a list rather than a
string (in accordance with the ls_host documentation), after which we have:
...
files_before: 'foo.1 foo.2 foo.3'
...

Tested on x86_64-linux.

Committed to trunk.

Thanks,
- Tom
