Created a new simple (very simple) approach to write binaries.

The old malelf_binary_write was renamed to malelf_binary_write_elf
and marked as deprecated. The old idea isn't necessary and a simple
write of all bin->mem is enough. The additional functions used by
malelf_binary_write_elf like malef_binary_write_(phdr,shdr,ehdr)
was maintained in code and can be usefull in the future.

In this commit I've fixed a bug in malelf_binary_add_phdr32. The
ehdr->e_phentsize wasn't adjusted to length of pht header when
adding new new phdr.

Tests to malelf_binary_write and malelf_binary_add_phdr32 were added
to tests/binary_test.c.

Fucking ugly commit ... sorry guys
