[PATCH] tests/tcg/multiarch: Give the 'memory' TCG test a larger timeout

[Peter Maydell]

The 'memory' TCG test times out intermittently on our cross-i686-tci
CI job. We expect this to be a slow config (it's using TCI), so it's
possible that when the CI runner is heavily loaded it tips past
the timeout.

Double the timeout for tests.  If this doesn't resolve the
intermittents we can assume we're looking at some kind of
TCI-specific hang.

I could not figure out a way to get the timeout to apply to the
'memory' test specifically (including all its variants like
running with plugins or the gdbserver or record-replay).

Ahh we crossed streams because I merged:

  cdb5bfc9f34 (tests/tcg: bump TCG test timeout to 120s)

Do we need even more time?

Ah, I missed that -- I'll let you know if I see this failure again.
