Allow /postinstall files to have custom contexts
We were mounting /postinstall with a 'context=...' option. This forces
all files within /postinstall to have a single selinux context,
limiting the possible granularity of our policies. Here we change it
to simply default to the 'postinstall_file' context for the 'system'
partition but allow individual files to have their own custom contexts
defined by /system/sepolicy. Other partitions retain the single
'postinstall_file' context.
The sample_images were updated to manually add a selinux label for
testing FS contexts.
