inventory_file relational path can break linchpin

[abraverm]

Setting inventory_file with relational path such as beaker.yml will overwrite lincpin file provision/beaker.yml.

Linchpin version: 1.5.4
Example:

---
inventory_layout:
  inventory_file: beaker.yml
  vars:
    hostname: __IP__
    ansible_user: root
  hosts:
    example_shit:
      count: 1
      host_groups:
        - example

Running linchpin up will overwrite ~/.virtualenvs/linchpin/lib/python2.7/site-packages/linchpin/provision/beaker.yml with the result inventory and thus breaking linchpin.

Expected result:
Workspace will be the relational path and ./beaker.yml will be create or modified.

@abraverm can you verify whether this issue still exists with the 1.6.0 release?
