[PATCH v4 0/4] Feature to use symbolic links to binaries for ptest

[Mariano Lopez <just.another.mariano@gmail.com>]

Some binaries are renamed by update-alternatives class at build time
and some ptest run against a binary belonging to another package. Take
for example busybox or util-linux.

This series adds a directory within the ptest with symlinks to the
binaries produced by the package, so just adding this directory to the
PATH will test the correct binaries.

To use this feature just add PTEST_BINDIR = "1" to the recipe.

v2 changes:

Add busybox recipe to use this method of symlinks generation.

Refactor the way the binary ptest directory is generated. Now the
directory will contain only symlinks to binaries that were renamed by
update-alternatives and not symlinks to all the package's binaries. This
have some advantages:
- Less lines and the code is cleaner.
- There is no need to have symlinks for every binary.
- Reuse existing update-alternatives functionality, don't need to add
  new features to the class.

v3 changes:

Fix white space mismatch

v4 changes:

Check for PTEST_ENABLED to add the functionality, this will solve the
issue when building nativesdk packages
