sys-apps/less: add 643-r1 (add certtool filters and system filter support)

1. Use certtool instead of openssl when appropriate

   - openssl only shows you the first certificate/entry it encounters
     and ignores the rest. Using certtool will correctly display all
     the entries in a single file. The view is also more readable with
     certtool.

   - Since openssl is still used as a fallback, not forcing a runtime
     dependency on `net-libs/gnutls[tools]`.

   - Java keystore filters were missing, so add them (jks/legacy and
     pfx/p12).

   - Also added a p12 file filter.

2. Add support for system filters

   - Looking for a way to add custom, system wide, filters to an image
     from other ebuilds (so the lessfilter is installed only when that
     package is installed).
