Patch to asdf-install to cope with certain tar files on cmucl

Hi,

asdf-install does not properly work when the first entry in the package tar 
file is the directory.  It the function install-package tries to determine the 
name of the created subdirectory by looking at tar's output.  It fails to 
correctly test parse the output, though, if the first line printed by tar is 
the name of the package subdirectory, without a trailing slash.

This patch fixes the wrong search for the character terminating the
subdirectory name.
