package/cups-filters: fix broken symlink in installation

The patch used previously to support versions of ln lacking the '-r'
option generated broken links:

    $ file target/usr/lib/cups/backend/driverless
    target/usr/lib/cups/backend/driverless: broken symbolic link to ../../usr/lib/cups/driver/driverless

Add a squashing of two patches already applied upstream that provide a
better solution:

    https://github.com/OpenPrinting/cups-filters/pull/154
    https://github.com/OpenPrinting/cups-filters/pull/157

Subject: [PATCH] install: don't use ln -r
Oldish enterprise-class distributions have too old versions of
coreutils, with ln not supporting -r.
So we fake it.
ln -r would create minimalist relative paths, but they are not
trivial to generate. Instead, we always create paths relative to the
root, i.e.:
ln -s -r /usr/bin/foo /usr/sbin/foo
would create: /usr/sbin/foo -> ../bin/foo
while we do : /usr/sbin/foo -> ../../usr/bin/foo

Subject: [PATCH] install: support old ln versions without the -r option
Oldish enterprise-class Linux distributions have outdated versions of
coreutils whose ln command do not support the -r option. Also non-Linux
systems like FreeBSD don't support that option. Use a shell script that
mimics the missing functionality.
The script creates minimalist relative paths, like ln -r does, but in
order to simplify the logic, it requires that the arguments be absolute
paths and do not end with '/'. This is enough for our purposes.
Add configuration logic to detect if ln supports the -r option, based on
the logic used by Autoconf to check if ln supports the -s option.
