This MR aims at updating the CTP7 sysroot to the most recent image that exists, including the perf
tool. See #227 for more details.
Please note how the PETA_SYSROOT
variable is renamed to GEM_SYSROOT
and the path changed to a versioned one.
Main step of #227
Deployed on gem904daq04
and the GE1/1 integration CTP7. Configuring the board and taking a run still possible.
