bug#6768: ls: fix a test failure that should have been skipped

[dsh]

Hi,

I just ran into this one test failure while building the latest sources.  The
test didn't really fail, but the exit via the function invoked in $() doesn't
terminate the test script, it simply terminates the substitution command.

Here are the bits where it failed:

++ inode_via_readdir /home/dsh/.gvfs
++ mount_point=/home/dsh/.gvfs
+++ basename /home/dsh/.gvfs
++ base=.gvfs
++ case $base in
++ skip_test_ 'mount point component starts with "."'
...
++ exit 77
+ readdir_inode=
++ env stat --format=%i /home/dsh/.gvfs
+ stat_inode=1
+ case $stat_inode in
+ test '' = 1
+ fail=1

This simple patch checks for a skipped test status and continues to the next
test.

* tests/ls/readdir-mountpoint-inode: Check to see if skip_test_ is
called in a helper function via $() instead of mistakenly failing.
