In the edge case when an updated package has different (or no)
alternatives groups, make sure to prune those that are in pkgdb
but not in the newly installed package.
A potentially common case of this is when a package that formerly
had alternatives gets removed and a transitional metapackage
takes its place (which has no alternatives).
When the new package has no dependencies, oldest next possible
alternatives group will be used. This is because that indicates
a removed package. When there are dependencies, the newest one
will be used; as this indicates a transitional package.
Even if the alternatives group is already registered, we need
to create the symlinks from current pkg dictionary (repo).

This fixes the new test case "less_entries_update" contributed
by @duncaen.
If "alternatives" dict from pkgdb differs from the one from repos,
find obsoletes and remove them.

Fix logic as found by @duncaen in #101.
Also set "first" when the entry is removed from the array.
Fixes#102

In the !current branch, "first" wasn't initialized so it displayed garbage:
Removing `pinentry-tty-1.1.0_5' ...
Removing 'pinentry' alternatives group symlink: pinentry
pinentry-tty-1.1.0_5: unregistered 'pinentry' alternatives group
Switched 'pinentry' alternatives group to 'p
o@�'
Creating 'pinentry' alternatives group symlink: pinentry -> /usr/bin/pinentry-tty
Removed file `/usr/bin/pinentry-tty'
Removed `pinentry-tty-1.1.0_5' successfully.
With my fix:
Removing `pinentry-tty-1.1.0_5' ...
Removing 'pinentry' alternatives group symlink: pinentry
pinentry-tty-1.1.0_5: unregistered 'pinentry' alternatives group
Switched 'pinentry' alternatives group to 'pinentry'
Creating 'pinentry' alternatives group symlink: pinentry -> /usr/bin/pinentry-tty
Removed file `/usr/bin/pinentry-tty'
Removed `pinentry-tty-1.1.0_5' successfully.

This commit adds relative link support to lib/package_alternatives.c.
Instead of creating absolute links, xbps will create relative links
to the target. This allows to follow links on systems even if the
aren't mounted on /.
