Entropy preserved libs handling code did not check all the followed symlink
before removing them. This causes the deletion of unexpected libraries during the
removal of packages. For example, app-emulation/vmware-workstation contains
the following symlink:
(A) /opt/vmware/lib/vmware/lib/libssl.so.1.0.1/libssl.so.1.0.1 -> (B) /usr/lib64/libssl.so.1.0.1
Upon removal of vmware-workstation, A is garbage collected and deleted,
if it's a symlink, the link is followed and (B) is removed as well, without
validating the action (i.e. checking if a package is still owning (B).)
This commit fixes this. See Sabayon bug #5812.
