eal: update assertion macro

Update RTE_VERIFY macro to make it possible to use complex expressions
in RTE_ASSERT.

Now it’s possible to have % char inside the expression, for example:
RTE_ASSERT((sizeof(some_struct) % 64) == 0)

Before the patch, “%" sign acts like a conversion specification
beginning character.

Fixes: 148f963fb532 ("xen: core library changes")
