- install libasan in physim containers
- run physim containers with SYS_CAP_PTRACE capability
- remove static-libasan: not available in RHEL8:
The physims are tested in a container environment on top of RHEL8. To
my knowledge, no package provides the static ASan library there.
Therefore, remove it here to be able to run these tests.
This commit creates an intermediary build image for all eNB, gNB, UE,
nrUE, RU targets (ran-build) after the image containing all RAN
compilation dependencies (ran-base). Then, the corresponding target
container images are just copied from the ran-build.
The only exception is phySim, which is still compiled independently, as
the build_oai would otherwise put all compiled files into
phy_simulators/build instead of ran_build/build. We do this at this
state to avoid any inconsistencies.
