e26aa6a385 chore(scripts): when running in non-interactive mode, do not enable neither start any driver. 
Eg: when building Falco docker image, and installing Falco package, we don't want it to build any driver.

41ffc90633 cleanup(scripts): allow falco-driver-loader script to manage more gcc versions. 
AmazonLinux uses `gcc-$Vers`, like gcc-10, but our regex prevented that to work.
Instead, rely on the fact that **real** gcc has some `--version` fixed output.

910b8ff858 Fix(engine) Save parse positions when finding unresolved macros 
Now that ASTs contain parse positions, use them when reporting errors
about unknown macros.

When doing the first pass to find all macro references, save macros as
a map<macro name,parse position> instead of a set<macro name>. While
making that change, change the visitor struct to use references
instead of pointers.

In the second pass, when reporting any unresolved macro references,
also report the parse position.

The unit tests also check that the positions of macros are properly
returned in the resolved/unresolved maps.

83b12bab1d Fix(engine): include parse positions in compile errors 
Now that ASTs have parse positions and the compiler will return the
position of the last error, use that in falco rules to return errors
within condition strings instead of reporting the position as the
beginning of the condition.

This led to a change in the filter_ruleset interface--now, an ast is
compiled to a filter before being passed to the filter_ruleset
object. That avoids polluting the interface with a lot of details
about rule_loader contexts, errors, etc. The ast is still provided in
case the filter_ruleset wants to do indexing/analysis of the filter.
