Ryan Barnett b3a6c7d3a3 package/ebtables: bump to version 2.0.11
With the version bump to 2.0.11, ebtables switch to autotools build
system. In addition, ebtables-{restore/save} moved to being installed
as ebtables-legacy-{restore/save}.

Changes to support this version bump include:

 * Remove dependency on !BR2_STATIC_LIBS for ebtables-restore as the
   switch to autotools supports compiling with static libraries.
 * Update ebtables-save script patch to use /usr/sbin/ebtables-legacy
 * Remove 0001-*-ethernetdb*.patch as it was merged with commit:
     http://git.netfilter.org/ebtables/commit/?id=f8079671326e9fd079391d24911a9a8a77f1d6fd
 * Remove 0002-*-musl-*.patch as support was added with commit:
     http://git.netfilter.org/ebtables/commit/?id=9fff3d5f9da00255463d28b38d688c25025b7fb1

Subject: [PATCH] ebtables: replace ebtables-save perl script with bash rewrite
Fedora provides a bash replacement for the default ebtables-save perl
script. Using it allows the ebtables run-time dependency on perl to
be replaced with a runtime dependency on bash - which is lower
overhead and more likely to be present on typical embedded systems
already.
