lxc: add missing deps

Several deps are missing based the output of lxc-checkconfig shown below
before this commit is applied.

CONFIG_IP_NF_TARGET_MASQUERADE and CONFIG_IP6_NF_TARGET_MASQUERADE are
only needed for lxc-net which we do not package.

% lxc-checkconfig | grep missing
Cgroup device: missing
CONFIG_IP_NF_TARGET_MASQUERADE: missing
CONFIG_IP6_NF_TARGET_MASQUERADE: missing
CONFIG_NETFILTER_XT_TARGET_CHECKSUM: missing
FUSE (for use with lxcfs): missing
checkpoint restore: missing
CONFIG_UNIX_DIAG: missing
CONFIG_INET_DIAG: missing
CONFIG_PACKET_DIAG: missing
CONFIG_NETLINK_DIAG: missing

Additionally, two new patches have been added which remove checks for
options that OpenWrt currently does not package and can serve are
false positives for missing items from our kernel config, namely:
lxc-net and lxc-checkpoint

After applying this commit, below is the output showing that the kernel
config[1] should pass all tests for functionality:

% CONFIG=config ./lxc-checkconfig
