This should prevent the race between gzserver and gz model and fix the
integration tests which sometimes timeout because the model is not
spawned correctly.
This patch also changes the shebang to what's generally recommended.
If `make px4_sitl_default` is run, and not `make px4_sitl_default gazebo` then each model instance will throw the following errors:

ce1eca2 2020-07-19 Daniel Leonard Robinson - New vehicle type: Airship (#490)
df186d2 2020-07-18 TSC21 - use 'EnableC++XX' and remove duplicated compiler sets
60e5d4e 2020-07-18 TSC21 - remove the check for the 'px4' binary (it's never found since it's built in parallel with sitl_gazebo)
a3b5c5e 2020-07-19 JaeyoungLim - Fix moment calculation (#545)
07820ee 2020-07-19 JaeyoungLim - Fix gimbal imu sensors intefering with each other (#549)
- Spaces -> tabs.
- Remove "brew install python" because it's already a dependency of the
px4-dev tap.
- Remove "brew install ccache" as we can also add it to the px4-dev tap.
- Don't try to update pip installation, it works fine as is.
- Install pip dependencies as user, no need for system-wide install.

1cd16d7 2020-06-18 JaeyoungLim - Set GPS utc time to use utc time (#522)
- remove all remaining IOCTLs for accel and gyro and handle all calibration entirely in sensors module with parameters
- sensor_accel and sensor_gyro are now always raw sensor data
- calibration procedures no longer need to first clear existing values before starting
- temperature calibration (TC) remove all scale (SCL) parameters
- gyro and baro scale are completely unused
- regular accel calibration scale can be used (CAL_ACC*_xSCALE) instead of TC scale
