Subject: vim-patch:9.0.1874: CI may fail in test_recover_empty_swap

Problem:  CI may fail in test_recover_empty_swap
Solution: Set directory option

Fix failing Test_recover_empty_swap test

:recover by default not only looks in the current directory, but also in
~/tmp for files to recover. If it finds some files to recover, it will
interactively prompt for a file to recover. However, prompting doesn't
work when running the test suite (and even if it would, there is no one
that can answer the prompt).

So it doesn't really make sense during testing, to inspect different
directories for swap files and prompt and wait (which will lead to a
timeout and therefore a failing test).

So set the 'directory' option temporarily to the current directory only
and reset it back once the test finishes.

closes: vim/vim#13038

Subject: fix(oldtest): always use a 64-bit int for swapfile block number

09d4133 changed blocknr_T from long to int64_t, so pe_bnum is now always 64-bit.  This was an incompatible change in the swapfile format for 32-bit systems, but there have been no complaints in the past 9 years so just adjust the test.
