fs/compat.c: fix build on MIPS/s390

The definition of PAGE_CACHE_MASK in <linux/pagemap.h> is needed to use MAX_RW_COUNT, and on x86-64 that gets done indirectly through the architecture header includes. But on MIPS and s390 that doesn't happen, and we need to make sure that fs/compat.c includes pagemap.h explicitly. Introduced in commit 435f49a ("readv/writev: do the same MAX_RW_COUNT truncation that read/write does").
