radare2: Add patch to default to AT&T ASM syntax

Some personal history on this:

I started to get used to AT&T syntax because it's the default in GDB and
used that ever since until I one day starting to do some more reverse
engineering using radare, which defaults to Intel syntax.

Ever since then probably my most used command in GDB was "set
disassembly-flavor intel" (because I was to lazy to add it to the
config) because I constantly got confused by the source/destination
operand swaps. This even happened during live reverse engineering at rC3
where I was confused about some function logic only to find out that I
was viewing in AT&T syntax.

Fast-forward to today: I'm debugging some application using WINE and
winedbg uses AT&T syntax, which I didn't like at first. After reflecting
on this for a while, I thought it would probably be better to get used
to AT&T syntax again and switch everything to use AT&T for the following
reasons:

  * Operands are more natural to read, since most libraries/APIs in
    higher level languages do it like this (well, except memcpy, strcpy,
    etc... maybe I now get confused by libc functions...)
  * AT&T syntax feels less verbose, for example "mov ecx, dword [eax]"
    is just "movl (%eax), %ecx"

This very commit makes sure that radare2 now defaults to AT&T syntax
instead of eg. ensuring that GDB uses Intel syntax by default.
