build: add missing module for jit.dump on ARM64

Since commit c9d88d5 ('Fix #984: add
jit.* library to the binary') all required modules implemented in Lua
are bundled (i.e. compiled into the executable as a C literal) into
Tarantool binary. While making Tarantool work on ARM64 platforms, it
turned out the arch-specific module (namely, jit/dis_arm64.lua) is not
bundled. Within this patch the missing sources are added and jit.dump
works fine on ARM64 hosts as a result.

Part of #5983
Relates to #5629
Follows up #984
