scripts/gdb: support getting current task struct in UML
A running x86 UML kernel reports with architecture "i386:x86-64" as it is
a sub-architecture. However, a difference with bare-metal x86 kernels is
in how it manages tasks and the current task struct. To identify that the
inferior is a UML kernel and not bare-metal, check for the existence of
the UML specific symbol "cpu_tasks" which contains the current task
struct.
