keymaster: Remove usage of PAGE_SIZE

Browse source 
bionic provides PAGE_SIZE macro which happens to also match the
size keymaster send buffer (4096) and half the size of the recv
buffer.

PAGE_SIZE is being removed as no other libc provides this and
Android is moving towards being page-size-agnostic.

Use a 4096 constant instead.

Test: Boot 16k device
