[build] Pad .rom, .dsk, and .hd images to 512-byte boundaries

Browse Source 
QEMU will silently round down a disk or ROM image file to the nearest
512 bytes.  Fix by always padding .rom, .dsk and .hd images to the
nearest 512-byte boundary.

@@ -47,13 +47,13 @@ To get qemu running is fairly simple:
8. Build gPXE floppy disk images and pad to 1.44MB
pushd ../../src
make bin/rtl8139.pdsk
make bin/rtl8139.dsk
popd
9. Start qemu
./qemu/i386-softmmu/qemu -L qemu/pc-bios \
-net nic,model=rtl8139 -net tap,ifname=tap0 \
-boot a -fda ../../src/bin/rtl8139.pdsk
-boot a -fda ../../src/bin/rtl8139.dsk
You should see qemu start up, load up gPXE and attempt to boot from
the network.
