BUG: set numpy requirement for aarch64 and py3.9

[aptalca]

It is stated in this file on line 13 that # Aarch64(Python 3.9 requirements are the same as AMD64)
However, the python 3.9 numpy requirement is excluding aarch64, therefore there is no aarch64 numpy requirement defined at all for py3.9.
When one tries to build pandas from source on aarch64 with py3.9 (such as alpine 3.14, which is musl based), there is no matching numpy found and therefore the build fails.

This commit sets the numpy version requirement for aarch64 on py3.9 the same as amd64 as stated.

Here's a log of a failed build:
