um: remove PAGE_SIZE alignment in linker script causing kernel segfault.

The linker script cleanup that I did in commit 5d150a97f93 ("um: Clean up
linker script using standard macros.") (2.6.32) accidentally introduced an
ALIGN(PAGE_SIZE) when converting to use INIT_TEXT_SECTION; Richard
Weinberger reported that this causes the kernel to segfault with
CONFIG_STATIC_LINK=y.

I'm not certain why this extra alignment is a problem, but it seems likely
it is because previously

__init_begin = _stext = _text = _sinittext

and with the extra ALIGN(PAGE_SIZE), _sinittext becomes different from the
rest.  So there is likely a bug here where something is assuming that
_sinittext is the same as one of those other symbols.  But reverting the
accidental change fixes the regression, so it seems worth committing that
now.
