opkg-utils: Fix silent empty/broken opkg package creation

opkg-build was failing on hosts where tar < 1.28 and reproducibile builds
were enabled but it was doing this silently and generating corrupted
(empty) ipk files. Add a fix for this (submitted upstream).

The fix requires bash but if you're building ipk files this shoudn't be
a problem.

+We need opkg-build to fail if for example the tar command is passed invalid 
+options. Without this, we see silently created empty packaged where data.tar
+is zero bytes in size. This creates hard to debug problems.
+
+An example is when reproducible builds are enabled and run on old hosts like
+centos7 which has tar < 1.28:
+
+Subprocess output:tar: unrecognized option '--clamp-mtime'
+Try `tar --help' or `tar --usage' for more information.
