apparmor: fix implicit declaration of function 'decompress_zstd'

Browse source

When CONFIG_ZSTD_DECOMPRESS is not enabled, and neither
CONFIG_SECURITY_APPARMOR_EXPORT_BINARY nor
CONFIG_SECURITY_APPARMOR_COMPRESSED_POLICY are enabled.

The build will fail with implicit declaration of function
'decompress_zstd' because there is not an appropriate stub function,
for when the zstd decompression isn't enabled.

In addition fix compress_min, and compress_max to be conditional on
CONFIG_SECURITY_APPARMOR_EXPORT_BINARY, as they are used with the
exported policy.
