[Click] patchless click patches

[Sascha Alexander Jopen]

Hello,

the FromHost element simply does not exist after compiling. ToHost,
ToHostSniffers and ToDevice, as well as FromDevice, are compiled,
FromHost not.
When feeding a click script to click-install the following error is emitted:
<stdin>:144: unknown element class 'FromHost'

fromhost.cc contains
ELEMENT_REQUIRES(AnyDevice linuxmodule false)
The 'false' requirement, may be this prevents compiling this element?
