Fix assumption that DRI_DEVNAME begins at 0 (#5865) 
* Fix assumption that DRI_DEVNAME begins at 0

The existing logic of the code was to count every possible entry in
KMSDRM_DRI_PATH. After this a for loop would start trying to open
filename0, filename1, filename2, etc. In recent Linux kernels (say
5.18) with simpledrm, the lowest KMSDRM_DRI_DEVNAME is often
/dev/dri/card1, rather than /dev/dri/card0, causing the code to fail
once /dev/dri/card0 has failed to open. Running:

modprobe foodrm && modprobe bardrm && rmmod foodrm

before you try to run an application with SDL KMSDRM would have also
made this fail.

* Various changes from review

- Removed newline and period from SDL error
- Explicitely compare memcmp to zero (also changed to SDL_memcmp)
- Changed memcpy to strncpy
- Less aggressive line wrapping

* Various changes from review

- strncpy to SDL_strlcpy
- removed size hardcodings for KMSDRM_DRI_PATHSIZE and
  KMSDRM_DRI_DEVNAMESIZE
- made all KMSDRM_DRI defines, run-time variables to reduce bugs caused
  by these defines being more build-time on Linux and more run-rime on
  OpenBSD
- renamed openbsd69orgreater variable to moderndri
- altered comment from "if on OpenBSD" to add difference in 6.9

* Various changes from review

- Use max size of destination, rather than max size of source
- Less hardcodings
