[PATCH 3/6] pack-bitmap.c: drop unnecessary 'inline's

[Taylor Blau <me@ttaylorr.com>]

Both `read_be32()` and `read_u8()` are defined as inline dating back
to b5007211b6 (pack-bitmap: do not use gcc packed attribute,
2014-11-27), though that commit does not hint at why the functions were
defined with that attribute.

However (at least with GCC 12.2.0, at the time of writing), the
resulting pack-bitmap.o contains the same instructions with or without
the inline attribute applied to these functions:

    $ make O=3 pack-bitmap.o && mv pack-bitmap.o{,.before}
    [ apply this patch ]
    $ make O=3 pack-bitmap.o && mv pack-bitmap.o{,.after}
    $ objdump -d pack-bitmap.o.before >before
    $ objdump -d pack-bitmap.o.after >after
    $ diff -u pack-bitmap.o.{before,after}

    -pack-bitmap.o.before:     file format elf64-x86-64
    +pack-bitmap.o.after:     file format elf64-x86-64

     Disassembly of section .text:

So defining these functions as inline is at best a noop, and at worst
confuses the reader into thinking that there is some trickier reason
that they are defined as inline when there isn't.

Since this pair of functions does not need to be inlined, let's drop
that attribute from both `read_u8()` and `read_be32()`.
