linux-user: Remove pgb_dynamic alignment assertion

The assertion was never correct, because the alignment is a composite
of the image alignment and SHMLBA.  Even if the image alignment didn't
match the image address, an assertion would not be correct -- more
appropriate would be an error message about an ill formed image.  But
the image cannot be held to SHMLBA under any circumstances.
