Subject: [PATCH] BUILD: make DeviceAtlas easier to build by defaulting to
 DEVICEATLAS_SRC

Since both DEVICEATLAS_INC and DEVICEATLAS_LIB are set to the same path
when building from sources, simply allow DEVICEATLAS_SRC to be set alone
to simplify the build procedure.

 the API source code from https://deviceatlas.com/deviceatlas-haproxy-module and
 once extracted :

+Optionally DEVICEATLAS_INC and DEVICEATLAS_LIB may be set to override the path

 These are supported DeviceAtlas directives (see doc/configuration.txt) :
