Use newer lager version to fix compilation issue
Use newer lager version to fix compilation issue

Lager version 2.0.0rc2 had `{included_applications,[syntax_tools,goldrush]}` in
its rebar.config file, which breaks other software that uses syntax_tools.

This is fixed in
https://github.com/basho/lager/commit/169cffd94759e99e2e8870b125861a91e3c1482a
and discussed in https://github.com/basho/lager/pull/140, so I'm updating to a
newer commit.
