src/arch/x86/bootblock.ld: Preserve space for the .init section

The .init section, which is placed right after the .text section in the
bootblock, is currently not taken into account when the start address for
the .text section is computed. Since it is quite small (just ~200-300
byte) it usually fits into the space which is created by aligning the
.text section to 4k. There are cases where it does not fit into this
space and therefore a section overlap between .text and .init happens at
link time. This in the end leads to a build error when the bootblock is
linked.

This patch considers the size of the .init section when the start
address of .text is computed so that it always fits.
