In order to meet the addon signing requirement for tests, specialpowers
needs to be installed at gecko runtime. This means it must be restartless.
This patch packages specialpowers as a restartless addon, but it does not
yet install it at runtime.

Some mochitests needs to behave differently when ran on B2G Desktop.
Currently, this is implemented using user agent string detection,
mostly relying on "Mobile" being present and "Android" being absent.
This is only true on B2G Desktop when ran on Try because the mozconfig
defined FXOS_SIMULATOR and that, per bug 1115935, this substring is only
added in this case, but not if just MOZ_B2G is defined. A better
approach is to expose 'isB2G' in SpecialPowers for this kind of
detection.
