Arm backend: Don't fall back to TOSA-1.0+INT in case of exception

aot_arm_compiler.py silently fell back to TOSA-1.0+INT in case the
user-provided TOSA spec could not be created. This may easily mislead
the user by hiding actual errors with the input to the program. Change
aot_arm_compiler.py to instead raising the exception in case the
user-provided TOSA spec can not be created.
