[PATCH] Do not install shell libraries executable

[Jonathan Nieder <jrnieder@gmail.com>]

These scripts are expected to be sourced instead of executed on
their own.  Avoid some confusion by not marking them executable.

The executable bit was confusing the valgrind support of our test
scripts, which assumed that any executable without a #!-line
should be intercepted and run through valgrind.  So during
valgrind-enabled tests, any script sourcing this file actually
sourced the valgrind interception script instead.

It was also confusing dpkg-shlibdeps, so I recently came up with
this fix.  Both fixes seem like good changes to me, and both
could be applied.  Your fix has the virtue of being shorter,
hence safer.
