files and removefiles not working inside a filter

Before opening a new issue, please use the issue search feature to see if a similar issue already exists. If not, please help us help you by filling in the template below.

What are you trying to do?
I'm trying to build a library that has separate files for all platforms

What problem are you having?
When using files inside a filter no files are added and when using removefiles inside a filter no files are removed

What have you tried so far?
When using files inside a filter did not work I tried using removefiles inside a filter
What version of Premake are you using?
5.0.0-dev

Anything else we should know?
An example:

project "hidapi"
	kind "StaticLib"
	language "C"

	location "../projects/hidapi"

	includedirs {"../externals/hidapi/hidapi/"}

	files {"../externals/hidapi/hidapi/hidapi.h", "../externals/hidapi/linux/hid.c", "../externals/hidapi/windows/hid.c", "../externals/hidapi/windows/hidapi_winapi.h"}

	filter "system:linux"
		removefiles {"../externals/hidapi/windows/hid.c", "../externals/hidapi/windows/hidapi_winapi.h"}

	filter "system:windows"
		removefiles {"../externals/hidapi/linux/**"}

here, the windows files aren't removed on linux and the linux files aren't removed on windows

(You can now support Premake on our OpenCollective. Your contributions help us spend more time responding to issues like these!)

Reproduce the issue using the provided Premake project and platform-specific filter example. Check how files and removefiles are processed within system filters, then verify that each platform excludes the other platform's files while retaining its own files.
