Fix meson build under Docker Tooling (eclipse-cdt#491)

* Fix meson build under Docker Tooling

- add new IToolChainConstants containing SECCOMP_UNCONFINED property constant
- add new setLauncher() method to CBuildConfiguration so that
  watchProcess() can be used for container building
- enhance ContainerCommandLauncher to discover specification of
  SECCOMP_UNDEFINED boolean option for execute() so "seccomp=undefined" can be specified
- fix ContainerCommandLauncherFactory.verifyIncludePaths() to only
  look at filtered includes that have been made absolute and to
  recognize matches when the prefix shows up in the loaded list
- add setting a property to ContainerGCCToolChain to set SECCOMP_UNCONFINED to true
  by default for the time-being
- when generating scannerinfo, specify "seccomp=unconfined"
- in ContainerGCCToolChain.startBuildProcess() remove extraneous
  banner statement and ensure that the build directory is created
- fixes eclipse-cdt#479
