augeas: bump to version 1.9.0

Add two patches from upstream to fix a build issue when building an
example. Ideally, the examples should not be build at all. However,
upstream disliked the idea of adding configure options like
`--disable-examples` [1]. So we'll make do with the patches and force a
autoreconf.

Additionaly, the signature was checked and a hash for the license file
is added.

+Subject: [PATCH] * examples/Makefile.am: do not force static linking of dump
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Forcing static linking of 'dump' was accidentally left in from some
+testing; there is no reason to force that specifically for dump.
+
+Thanks to Jörg Krause for reporting the issue and verifying the fix.
