fil_crypt_rotate_page - space_id should be compared to TRX_SYS_SPACE not space

Fixes compile error that highlights problem:

/source/storage/innobase/fil/fil0crypt.cc: In function 'void fil_crypt_rotate_page(const key_state_t*, rotate_thread_t*)':
/source/storage/innobase/fil/fil0crypt.cc:1770:15: error: ISO C++ forbids comparison between pointer and integer [-fpermissive]

Signed-off-by: Daniel Black <daniel.black@au.ibm.com>

Also, some MDEV-11738/MDEV-11581 post-push fixes.

In MariaDB 10.1, there is no fil_space_t::is_being_truncated field,
and the predicates fil_space_t::stop_new_ops and fil_space_t::is_stopping()
are interchangeable. I requested the fil_space_t::is_stopping() to be added
in the review, but some added checks for fil_space_t::stop_new_ops were
not replaced with calls to fil_space_t::is_stopping().

buf_page_decrypt_after_read(): In this low-level I/O operation, we must
look up the tablespace if it exists, even though future I/O operations
have been blocked on it due to a pending DDL operation, such as DROP TABLE
or TRUNCATE TABLE or other table-rebuilding operations (ALTER, OPTIMIZE).
Pass a parameter to fil_space_acquire_low() telling that we are performing
a low-level I/O operation and the fil_space_t::is_stopping() status should
be ignored.

specify BUILD_BYPRODUCTS, ninja needs it

that is, download AWS SDK there, not into the builddir root.
and .gitignore them all.

into non-standard compiler/linker path (e.g vcpkg on Windows).

Also fix linking with static preinstalled aws c++ sdk libraries
