pkg/instance: use -fpermissive -w when building old syzkaller

Browse Source 
Since we can be building very old revisions for bisection here,
make the build as permissive as possible.
Newer compilers tend to produce more warnings also kernel headers may be broken, e.g.:
ebtables.h:197:19: error: invalid conversion from ‘void*’ to ‘ebt_entry_target*’
