Added: Export additional primary TERMUX_* scoped shell environment variables

Browse source 
- TERMUX__ROOTFS
- TERMUX__HOME
- TERMUX__PREFIX
- TERMUX_APP__DATA_DIR (Actual app data directory path assigned by Android for the `com.termux` app returned by `ApplicationInfo`)
- TERMUX_APP__LEGACY_DATA_DIR (Expected legacy app data directory path for the `com.termux` app, mainly accessible on primary user `0` and is a symlink/bind mount to/from `TERMUX_APP__DATA_DIR`)
- TERMUX_APP__BUILD_DATA_DIR (App data directory path used by `termux-packages` `properties.sh` while building packages and `TermuxConstants.java` while building Termux app)
- TERMUX__SE_PROCESS_CONTEXT (SeLinux process context for current process)
- TERMUX_APP__SE_FILE_CONTEXT (SeLinux file context for the `TERMUX_APP__DATA_DIR`)
- TERMUX_APP__SE_INFO (Termux app seInfo tag found in selinux policy used to set app process and app data files selinux context)

This is also required for `libtermux-exec-*-ld-preload.so` `$LD_PRELOAD` library as well for `termux-exec` version `>= 2.0.0`.
