Declare dependency on android_filesystem_config.h

android_filesystem_config.h comes from a directory outside bionic/libc
so it can't be referenced directly, add it as a source file through
a filegroup module.

Test: builds
Test: libc rebuilds after touch system/core/include/private/android_filesystem_config.h
