The address of fp->path_name could be unaligned since seeking into the
device path buffer for a given node could end in byte boundary.
The fix is using aligned buffer allocated by grub_malloc for receiving
the converted UTF16 string by grub_utf8_to_utf16 and also the processing
after. The resulting string then gets copied to fp->path_name.

The catkey->name could be unaligned since the address of 'void* record'

The fix is using aligned buffer allocated by grub_malloc for holding
the UTF16 string copied from catkey->name. And use that buffer as
argument for grub_utf16_to_utf8 to convert to UTF8 strings.
In addition, using a new copy of buffer rather than catkey->name itself
for processing the endianess conversion, we can also get rid of the hunk
restoring byte order of catkey->name to what it was previously.

end of the linux_i386_kernel_header is at 0x202 + the byte value at 0x201 in
the linux_i386_kernel_header. So, calculate the size of the header using the
end of the linux_i386_kernel_header, rather than assume it is the size of the
linux_kernel_params struct.
Additionally, add some required members to the linux_kernel_params
struct and align the content of linux_i386_kernel_header struct with
it. New members naming was taken directly from Linux kernel source.
