Refactor the PT_WRITE*/PT_READ* and PIOD_* ATF ptrace(2) tests 

Merge all the PT_WRITE*/PT_READ* and PIOD_* the test cases into the common
body.

Changes:
 - treat D and I variations exactly the same
 - stop testing 2-3-4 attempts to perform the same read/write operation
 - stop testing interlocked (handshake) read/write operations
 - rename the tests
 - test write to .text section (with D and I type of operations)

New tests:
 - bytes_transfer_piod_read_d_8
 - bytes_transfer_piod_read_d_16
 - bytes_transfer_piod_read_d_32
 - bytes_transfer_piod_read_d_64
 - bytes_transfer_piod_read_i_8
 - bytes_transfer_piod_read_i_16
 - bytes_transfer_piod_read_i_32

 - bytes_transfer_write_i_text
 - bytes_transfer_piod_read_auxv

These tests are now covering all usual code paths.

All tests pass.
The PaX MPROTECT violating ones automatically detect whether to be skipped.

Eliminated 4x more code than removed.
