[core-server-kit] Can't emerge `www-server/lighttpd` due to `python-2.7` removal, needed for dep `dev-libs/ligbamin`

```
Calculating dependencies... done!

emerge: there are no ebuilds to satisfy ">=dev-lang/python-2.7.5-r2:2.7".
(dependency required by "dev-libs/libgamin-0.1.10-r5::dev-kit[python_targets_python2_7,python]" [ebuild])
(dependency required by "www-servers/lighttpd-1.4.79::core-server-kit" [ebuild])
(dependency required by "lighttpd" [argument])
```

We have the most recent version of `libgamin`.

Maybe the way to proceed here is to remove the Python dep from `libgamin` entirely, since it was never updated to `python-3.x`.

`$ emerge USE=-python lighttpd`:
```
Calculating dependencies... done!
[ebuild N ] dev-libs/libgamin-0.1.10-r5::dev-kit USE="-debug -python -static-libs" PYTHON_TARGETS="python2_7" 0 KiB
[ebuild N ] www-servers/lighttpd-1.4.79::core-server-kit USE="bzip2 ipv6 pcre ssl xattr zlib -dbi -doc -fam -kerberos -ldap -libev -libressl -lua -minimal -mmap -mysql -php -postgres -rrdtool -sasl (-selinux) -sqlite -test -webdav" 0 KiB
```

Start by reproducing the reported `emerge lighttpd` failure and inspect the `dev-libs/libgamin-0.1.10-r5` dependency metadata, including the Python USE flag. Done means lighttpd can emerge after Python 2.7 removal without requiring the unavailable dependency, while the existing `USE=-python` path remains valid.
