exec: fix TB invalidation after breakpoint insertion/deletion
tb_invalidate_phys_addr has to be called with the exact physical address of
the breakpoint we add/remove, not just the page's base address.
Otherwise we easily fail to flush the right TB.
This breakage was introduced by the commit f3705d5329 "memory: make
phys_page_find() return an unadjusted".
This appeared to work for some guest architectures because their
cpu_get_phys_page_debug implementation returns full translated physical
address, not just the base of the TARGET_PAGE_SIZE-sized page.
