chrony: fix build failure for arma9
Eliminate references to syscalls not available
for ARM_EABI. Also add a dependency on libseccomp
which is needed for scfilter to work.
Set PACKAGECONFIG to not enable scfilter, since
kernel CONFIG_SECCOMP is unlikely to be set. This
aligns the usage of libseccomp with that of other packages.
