Subject: [PATCH] Mk/Uses/cabal.mk: Replace shell process in EXECUTABLES
 wrapper scripts

The wrapper scripts leave the shell running for no reason.  Add an
exec to replace the shell process.

Before:
$ ps -d
35230  5  Ss    0:00.09 -oksh (oksh)
35351  5  S+    0:00.00 - /bin/sh /usr/local/bin/shellcheck -
35352  5  S+    0:00.00 `-- /usr/local/libexec/cabal/shellcheck -

After:
$ ps -d
35230  5  Is    0:00.05 -oksh (oksh)
35236  5  I+    0:00.01 - /usr/local/libexec/cabal/shellcheck -
