fix custom easyblock for bzip2 to ensure all versioned symlinks are created

[jfgrimm]

got some software explicitly linking libbz.so.1, the symlink for which we don't create (so it ended up using the OS bzip2 instead)

(created using eb --new-pr)

[Thyre]

LGTM otherwise, just needs some tests 😄

[Thyre]

Should we add a sanity check for the unversioned symlinks as well?

[boegel]

already done, we're already checking for lib/libbz2.so
