switch-libjpeg-turbo: include tjpeg library

[averne]

This fixes compilation of nx-hbmemu

[fincs]

Setting UNIX to true isn't really correct for our platforms and we intentionally avoided this in our toolchain files. Which codepaths does this enable that result in the turbojpeg API being repaired?

[averne]

Setting WITH_TURBOJPEG to true enables compilation of the turbojpeg library. However it also activates a test program for it that will fail to link unless UNIX is true (for libm). Unfortunately disabling that test program isn't possible afaict. https://github.com/libjpeg-turbo/libjpeg-turbo/blob/main/CMakeLists.txt#L667

The current package doesn't include turbojpeg.h (or .a):

Setting UNIX to true is never the right solution. Disabling test programs is always possible, As I've done with https://github.com/devkitPro/pacman-packages/commit/632cc0ebd2e9639c09f561e71de09c16d528e76e
