It's a combination of /etc/version and /etc/prettyversion.txt...

[root@kindle root]# cat /etc/version.txt /etc/prettyversion.txt
System Software Version: 004-juno_2_0_1_yoshi-167953

Kindle 5.1.2 (~~otaVersion~~)

More detail:
Spoiler:

This is straight from some (now dead) JBPatch code documentation:

/* The Amazon logic to determine the version seems to use the native
* libraries liblab126utilsjni and liblab126utils, to determine the
* "revision" of the Kindle from /etc/version.txt. Without having
* thoroughly decompiled everything, the device info
* "Kindle 5.1.0 (1557760049)" seems to stem from /etc/prettyversion.txt
* (for the first part), and the first line of /etc/version.txt:
* In this case it was:
* System Software Version: 049-juno_2_yoshi-155776
* So the "end" (155776), concatenated with the "beginning" (049), and
* some filler zeroes in between. */
