When using INSTALL_MASK to filter out files when installing (from .tbz2 binary packages) filter applies to folders or regular files but symlinks still get installed.

Expected Results: The /bin/uncompress symlink should not get installed as it's listed in INSTALL_MASK as is symlink's target. Note: in the past this worked correctly though I can't tell when it stopped working.
A probably important detail: If symlink target is masked by INSTALL_MASK the symlink is still installed even though listed in INSTALL_MASK. If symlink target is not masked (that it, it's being effectively installed), the symlink when masked by INSTALL_MASK does not get installed as expected. So for above example case, if /bin/gunzip was no covered by INSTALL_MASK, /bin/uncompress symlink would not get installed as requested by INSTALL_MASK.
It's a regression from this commit: https://gitweb.gentoo.org/proj/portage.git/commit/?id=5a1b870fe54ac06f864a648c3ea5cc118f6ce911
This is fixed in the master branch: https://gitweb.gentoo.org/proj/portage.git/commit/?id=f9d1791dbb8f61e836d1b453258502d800776bf2
Fixed in 2.2.27.
