Fix regcache::cooked_read_test selftest for mep
When running the regcache::cooked_read_test selftest in an all targets
build, I get the following internal error:
/home/simark/src/binutils-gdb/gdb/thread.c:95: internal-error: thread_info* inferior_thread(): Assertion `tp' failed.
The stack trace is the followiing:
#9 0x000055fe25584a52 in internal_error (file=0x55fe27a25fe0 "/home/simark/src/binutils-gdb/gdb/thread.c", line=95, fmt=0x55fe27a25c80 "%s: Assertion `%s' failed.")

The problems is that mep's code ends up calling inferior_thread, which
calls find_thread_ptid. find_thread_ptid searches for a thread by ptid
in the thread list of the inferior that is expected to contain that
thread.
However, the thread list of the mock inferior set up in cooked_read_test
is never initialized. So find_thread_ptid doesn't find the thread,
which is an unexpected situation for inferior_thread.
This is failing since this commit:
080363310650c93ad8e93018bcb6760ba5d32d1c
Per-inferior thread list, thread ranges/iterators, down with ALL_THREADS, etc.
Fix it by putting the mock thread in the thread list of the mock
inferior in cooked_read_test.
gdb/ChangeLog:
* regcache.c (cooked_read_test): Initialize thread list of
mock_inferior.
