Normalize property names for zfs receive

Browse Source 
It turns out, userland is much more happy with aliased property
names than the kernel is.

So let's normalize those to the expected names before we pass
them off.

Added a test case hacked up from the other recv -o/-x test that fails
on unpatched git and passes here.

# DESCRIPTION:
# Verify ZFS property override (-o) and exclude (-x) options work when
# receiving a send stream, using property name aliases
#
# STRATEGY:
# 1. Create a filesystem with children.
# 2. Snapshot the filesystems.
# 3. Create various send streams (full, incremental, replication) and verify
# we can both override and exclude aliased properties.
