TST: disable tests that fail due to bad alignment on sparc

(debian) sparc system malloc does not provide the alignment required by 16 byte
long double types this means the inout intent cannot be satisfied and several
tests fail as the alignment flag can be randomly true or fals when numpy gains
an aligned allocator the tests could be enabled again.
