[Buildroot] [git commit branch/2019.02.x] package/libsigrok: drop remnants of autoreconf

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=9a7c792b082ea91b63b7f49833b3731595e73c5e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.02.x

libsigrok has not needed autoreconf since b428801934 (package/libsigrok:
bump version to 0.4.0), 4 years ago now.

As such, we no longer need the autoreconf options, nor the dependency on
the autoconf archive.
