Seems like newer libseccomp versions start to freak out the sandbox as a whole. Testing on a CentOS 7 server with libseccomp-2.3.1 installed doesn't throw any errors and all tests pass. Anything newer then libseccomp-2.4 throws an error. Trying my own custom sandbox also throws the "Bad System Call" error on newer libseccomp, but functions perfectly on older.

Downgrading the linux kernel is currently the best solution for the current state of EasySandbox.

Lastly, the deprecation warning during compilation can be safely ignored on newer glibc.
