This commit reverts #3357.
The previous PR is for the new symbol NSEventMaskKeyDown, which is
introduced in #3347. In #3794, #3347 is reverted, so the workaround
in #3357 is no longer needed. Furthermore, it causes build failures
on 10.11 (#3932) as the header file for type NSEventMask is removed
in #3794, too.
Note that this is not a complete fix. A complete patch can be found
at [1]. In MacPorts, the OS version for building a package is the same
as the OS that installs it, so #ifdef can be used to replace @available.
The latter language feature is not available until Xcode 9.
With the patch mentioned in the previous paragraph, KeePassXC 2.5.1
can be built on Mac OS X 10.9 or newer.
