Always load ELF headers as part of the text segment.
This forces us to align the start of the text segment to its
declared alignment, otherwise the linker would be forced to allocate
address 0, which the kernel doesn't allow.
Instead of setting the start differently based on each platform's
declared text alignment, set it always to 0x400000 (4 MB),
which is greater than the largest alignment among the currently
supported platforms (amd64, 2MB alignment), and also aligns with
large pages on all platforms that support them.
