1.1.01

Per "man 5 cpio", the namesize in the cpio header includes the trailing
NUL byte of the pathname and the pathname is followed by NUL bytes, but
the current implementation ignores the trailing NUL byte when making
the newc header. Although make_header() tries to pad the pathname string,
the padding won't happen when strlen(name) + sizeof(struct newc_head)
is a multiple of 4, and the non-NULL-terminated pathname may lead to
unexpected results.

Assume that a file is created with 'echo -n aaaa > /boot/test12' and
loaded by grub2:

    linux /boot/vmlinuz
    initrd newc:test12:/boot/test12 /boot/initrd

The initrd command eventually invoked grub_initrd_load() and sent
't''e''s''t''1''2' to make_header() to generate the header:

00000070  30 37 30 37 30 31 33 30  31 43 41 30 44 45 30 30  |070701301CA0DE00|

                   ^^ end of the pathname

Since strlen("test12") + sizeof(struct newc_head) is 116 = 29 * 4,
make_header() didn't pad the pathname, and the file content followed
"test12" immediately. This violates the cpio format and may trigger such
error during linux boot:

    Initramfs unpacking failed: ZSTD-compressed data is trunc

To avoid the potential problems, this commit counts the trailing NUL byte
in when calling make_header() and adjusts the initrd size accordingly.

Now the header becomes

00000070  30 37 30 37 30 31 33 30  31 43 41 30 44 45 30 30  |070701301CA0DE00|

                      ^^ end of the pathname

Besides the trailing NUL byte, make_header() pads 3 more NUL bytes, and
the user can safely read the pathname without a further check.

To conform to the cpio format, the headers for "TRAILER!!!" are also
adjusted to include the trailing NUL byte, not ignore it.
