atop: fix minor()/major() build failure due to glibc 2.28

glibc 2.28 no longer includes <sys/sysmacros.h> from <sys/types.h>,
and therefore <sys/sysmacros.h> must be included explicitly when
major()/minor() are used. See glibc upstream commit:

  https://sourceware.org/git/gitweb.cgi?p=glibc.git;a=commitdiff;h=e16deca62e16f645213dffd4ecd1153c37765f17

This commit adds a patch to directly include <sys/sysmacros.h> into
photosyst.c where minor() and major() macros are used.

Patch has been taken from atop upstream pull request:

  https://github.com/Atoptool/atop/pull/35
