Gentoo user-packages: use qlist for missing-detect (handles non-binary pkgs)

Browse source 
The previous missing-detect used 'command -v <basename>' which
fails for packages that don't ship a binary of the same name
(zsh-completions installs /usr/share/zsh files, not
/usr/bin/zsh-completions). After the previous run installed these
packages, the next apply falsely reported them as missing and
tried to re-install them.

Switch to qlist -I which correctly reports whether a package is
in the installed-db. qlist is from app-portage/gentoolkit which
is already installed on gentoo. Fall back to equery, then to
the basename check, in case qlist is missing.

# Step 3: Determine what's missing
# gentoo's emerge has a "is it installed?" check via `qlist` or `equery`.
# Simpler: check if the binary is on PATH.
# Many gentoo packages don't ship a binary of the same name as the
# package (zsh-completions, zsh-syntax-highlighting install files into
# /usr/share/zsh, not /usr/bin). The simplest "is it installed?"
# check for our purposes is `qlist -I <pkg>` — returns 0 if the
# package is in the installed-db, 1 if not. But qlist is from
# gentoolkit and may not be available. Fall back to `equery`.
