loader: fix elf lookup_symbol type filtering

The existing logic doesn't seem to make much sense, as we won't filter
on the type if st_shndx != SHN_UNDEF. In practice, this breaks booting
12.3 kernels on newer loaders, as they do have a `kernphys` symbol of
the wrong type (NOTYPE, rather than OBJECT) -- we end up deriving the
wrong value for copy_staging.

It's unclear if this version makes any more sense, but it seems to match
what rtld's matched_symbol() does. Loader doesn't need to care about
STT_FUNC w/ UND shndx, because we won't encounter those; in kmods,
undefined (kernel) functions are NOTYPE.

stand: zfs: handle holes at the tail end correctly

This mirrors dmu_read_impl(), zeroing out the tail end of the buffer and
clipping the read to what's contained by the block that exists.

This fixes an issue that arose during the 13.1 release process; in
13.1-RC1 and later, setting up GELI+ZFS will result in a failure to
boot. The culprit is this, which causes us to fail to load geom_eli.ko
as there's a residual portion after the single datablk that should be
zeroed out.

Add support for getting early entropy from UEFI

UEFI provides a protocol for accessing randomness. This is a good way
to gather early entropy, especially when there's no driver for the RNG
on the platform (as is the case on the Marvell Armada8k (MACCHIATObin)
for now).

If the entropy_efi_seed option is enabled in loader.conf (default: YES)
obtain 2048 bytes of entropy from UEFI and pass is to the kernel as a
"module" of name "efi_rng_seed" and type "boot_entropy_platform"; if
present, ingest it into the kernel RNG.

powerpc64: fix loader regression

After b4cb3fe0e39a, loader started crashing on PowerPC64, with a
Program Exception (700) error. The problem was that archsw was
used before being initialized, with the new mount feature. This
change fixes the issue by initializing archsw earlier, before
setting currdev, that triggers the mount.
