  Use VEC for target_desc.reg_defs

The build log for this commit can be seen here:

  <https://gdb-build.sergiodj.net/builders/Ubuntu-AArch64-native-gdbserver-m64/builds/2696/steps/compile%20gdb/logs/stdio>

And the underlying problem is that the code is not calling the new
function "allocate_target_description" to allocate the "struct
target_desc" using "new" instead of XNEW, which end up not properly
initializing the fields of the structure.

Regtested on BuildBot.

* linux-low.c (handle_extended_wait): Use
"allocate_target_description" instead of "XNEW".
* linux-x86-low.c (initialize_low_arch): Likewise.
