Subject: mksh: add mkshrc when using TW_USE_TOOLBOX

Fixes broken shell prompt in Terminal and adb shell

Before: https://del.dog/7vphlkc
After: https://del.dog/vhkjgo8

Add as prebuilt with suffix "_twrp" to avoid conflict
with original mkshrc and rename via POST_INSTALL_CMD

Prebuilt version adjusts TMPDIR variable from
"/data/local/tmp" to "/tmp" for TWRP
