            Fix tsig-keygen and named-checkzone

Found out that multiple programs require fixed name and cannot contain
suffixes. This will fix those programs to run as designed and switch
versions. It affects:
- tsig-keygen
- ddns-confgen
- named-checkzone
- named-compilezone

This should make those tools to decide only based or starting part of
the program. Upstream supported suffix .exe, but we need support of
different suffixes. This change should work for both.

+Subject: [PATCH] Support program suffixes of tsig-confgen and ddns-confgen
+
+Suffixes different than .exe are used on Fedora. But those commands
+require exact names only. Allow switching between two variants only from
+prefix. That should work on all platforms. It should support also names
+like tsig-confgen-9.18 or tsig-confgen-9.20.
+
+The same case applies to named-checkzone and named-compilezone.
