07b4d5a47a fix(rules): use exit event in reverse shell detection rule 
In some cases the rule is not triggered when a reverse shell is spawned.
That's because in the rule we are checking that the file descriptor passed
as argument to the dup functions is of type socket and its fd number is "0, 1, or 2"
and the event direction is "enter".
The following event does not trigger the rule: dup2(socket_fd, STDIN_FILENO);
But using the exit event the rule is triggered.

bcda81f700 update(falco_scripts): Change Flatcar dynlinker path 
The Flatcar kernel module build needs to relocate binaries in /host/lib/modules
to run with the host's ld and glibc. While testing with glibc 2.34 that we plan
to introduce soon, we found that the previous dynlinker symlink (ld-xxx.so)
doesn't exist any longer. Update the hostld variable to use a path that is
present in all versions of glibc.

85f91a3ec4 update(falco_scripts): support pre-built module/probe on Flatcar 
Pre-built kernel modules/eBPF probes for Flatcar use the value of the OS
VERSION_ID field as KERNEL_RELEASE in the filename. A specific kernel release
version does not uniquely identify a Flatcar configuration, because Flatcar is
image-based instead of package-based. Here's a more specific example: the same
kernel version can be part of various Flatcar releases (across channels
alpha/beta/stable) with differences in configuration. This is why we use the
VERSION_ID value during offline builds with driverkit. Flatcar version numbers
are all higher than 1500.0.0, so there is no risk of collision with kernel
version numbers.

When locally building the kernel module on the system, we have access to the
correct kernel build directory at /lib/modules/$(uname -r)/build with the right
configuration and so for that branch, we need to reset KERNEL_RELEASE=$(uname -r).

See also the driverkit PR that introduces a builder for Flatcar:
