Subject: [PATCH] erts: Remove some external commands in Unix scripts

Remove calls to some external utilities (awk, basename, sed) in the
erl and start_erl scripts, replacing them with POSIX shell parameter
expansion and 'read' built-ins.

This improves compatibility with embedded systems and restricted
environments where these tools may be missing, particularly on older
releases of Android.

Notes on the shell built-ins used:

- "${0##*/}": A POSIX parameter expansion that removes the longest
  prefix matching '*/'. This pattern matches everything up to and
  including the last slash, effectively performing a 'basename'
  operation entirely within the shell.

- 'read -r VAR1 VAR2 < File': Read the first line of a file and
  assigns the first two space-separated words to each variable,
  replacing the 2 external calls to 'awk'.
