loader: Bump all versions to 3.0
Each incompatible change we make, we bump the major version. We've not
done the bump in a while, so sync everybody to 3.0. Anything older than
3.0 will be given a warning that their boot loader is too old. We check
only the major version, though, so minor versions can still be bumped
for individual loaders (though I honestly doubt we'll ever need to do
that again).

kboot: Use is_linux_error to check mmap return error
Rather than checking against the (incorrect) -511, use the
is_linux_error() function to check to see if host_mmap failed.

kboot: hostfs -- check for llseek failure correctly
The host_* syscalls are all raw Linux system calls, not the POSIX
wrappers that glibc / musl create. So we have to ranage change the
return value of host_llseek correctly to use the negative value hack
that all Linux system calls use.
This fixes a false positive error detection when we do something like
lseek(fd, 0xf1234567, ...); This returns 0xf1234567, which is a negative
value which used to trigger the error path. Instead, we check using the
is_linux_error() and store the return value in a long. Translate that
errno to a host errno and set the global errno to that and return
-1. lseek can't otherwise return a negative number, since it's the
offset after seeking into the file, which by definition is positive.
This kept the 'read the UEFI memory map out of physical memory' from
working on aarch64 (whose boot loader falls back to reading it since
there are restrictive kernel options that can also prevent it), since
the physical address the memory map was at on my platform was like
0xfa008018.

they are in the public domain.
