pactest: handle non-default scriptlet shells

pacman can be configured to use a different shell the /bin/sh for
scriplets.  Pass the cnfigured value to the pactest suite and make the
necessary "copy" of the shell in the test root.

Also update all copyright years in the pactest suite.

Remove leading / for pactest paths

The leading / makes the pactest suite look for the file in the users
filesystem.  This meant the ldconfig tests always passed (even when
broken in pacman...).

Make path to ldconfig configurable

The FHS (2.3) says having ldconfig in /sbin is optional and it is usually
located in /usr/sbin.  So /sbin/ldconfig should not be hard coded in
pacman.  Instead, provide a configure option --with-ldconfig that defaults
to the current path.

pacsort: add -f, --files option for sorting filenames

Teach pacsort to understand package filenames and optionally strip away
some of the context. alpm_pkg_vercmp() intentionally only understands
pure versions, so strings such as '18.0-2-x86_64' and '18.0.1-1-x86_64'
will be compared wrongly.

Partially addresses FS#33455.

Fix printing of paths

Originally printed a leading \ before all path names as the `' would be
removed during the make. Using '' should be just as good as using `'.

paccache.sh.in:
die "cachedir \`%s' does not exist or is not a directory" "$cachedir"

paccache
die "cachedir \%s does not exist or is not a directory" "$cachedir"
