Subject: [PATCH] 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.
