wam: revision bump, fix WAM on icefish

Included changes:
* a9e0093 Disable tinyproxy integration
* c0def20 [agl] Fix regex scanning
* c7b5db7 [agl] Handle hostname of application
* 4a00711 [agl] Retrieve token from environmen
* 7d4c91e Hard-code windowmanager roles for certain app ids
* files/trunc-webapp-roles.patch workaround repeated roles

Bumps WAM version and includes workaround for SPEC-3127. To
prevent repeated roles as much as possible, I'm using the
appid as a basis instead of "Webapp-" + host + port, which has
many chances to be redundant in the first 12 chars.
