app-crypt/sequoia-chameleon-gnupg: backport test fix

... but it doesn't get them passing yet. Ideas welcome! They don't pass
for me outside of Portage either, but way more _do_ pass outside of Portage
for me, as opposed to none right now inside.

+Subject: [PATCH] tests: Normalize underlines.
+
+  - GnuPG emits a header with underlines in key listings that changes
+    with the length of GNUPGHOME.  Now, since the state directories
+    are created within TMPDIR, the length of both GNUPGHOME and the
+    underline changes.  Previously, we normalized GNUPGHOME, but we
+    failed to normalize the underline.
+
+  - Fixes #8.
