Add signing of px4 binary into makefiles 

When an environment variable "SIGNING_TOOL" is defined, the make will
call this with two filename arguments: <input> and <output>.

The SIGNING_TOOL will read in the binary from input, and append
signature to the output. For example:

SIGNING_TOOL=${PWD}/Tools/cryptotools.py make px4_fmu-v5_default

Will use the example "cryptotools.py" to sign the px4_fmu-v5.bin
