mips64: Correct the value for the VG_MIN_MALLOC_SZB

The VG_MIN_MALLOC_SZB was incorrectly defined for MIPS64.
The incorrect value was 8 and the correct value is 16.
Fixes massif/tests/big-alloc for MIPS64.

mips64: Add a test case for mips64.

Add a function in the memcheck/tests/leak-segv-jmp.c for MIPS64
that execute the syscall. Because we added the mips64 case we 
need to change the line number in *.exp file.
Fixes memcheck/tests/leak-segv-jmp for MIPS64.

mips64: Wrong address size.

On MIPS64 address of 'undefined' can be 64-bit width.
When we are trying to access that address we need to use 0x%lx
instead of 0x%x.
Fixes gdbserver_tests/mcvabits for MIPS64.
