[PATCH] gdb: fix xtensa build with custom overlay

[Max Filippov <jcmvbkbc@gmail.com>]

The commit 14e361d7aa3bbd8601b0457ee8558344e444c651 ("xtensa-config.c:
missing defs.h include") fixed the build of default xtensa configuration
by including defs.h in the beginning of xtensa-config.c. Unfortunately
this fix doesn't work when gdb is configured for another xtensa core, as
the file xtensa-config.c is a part of configuration overlay and it gets
overwritten. To fix the build for all existing configurations include
defs.h into gdb/xtensa-tdep.h, where the issue (reference to undeclared
uint32_t) actually is.
