LU-9580 tests: remove performance-sanity tests from ALWAYS_EXCEPT

LU-9580 tests: remove performance-sanity tests from ALWAYS_EXCEPT

Remove performance-sanity tests 1 and 2 from ALWAYS_EXCEPT
list as well as tests test_1 and test_2 because all they
contain are calls to echo.
Tests 1 and 2 are associated with bugzilla ticket 15266 and
it is fixed. Yet, reviewing all comment in that ticket
reveals that tests 1 and 2 were never implemented.

Test-Parameters: trivial testlist=performance-sanity
