You have two misunderstandings here:

1. as to <arg value="something"/>: this will bundle what is in value
in only one argument to the command line. Writing ls -l is not the
same AT ALL than writing "ls -l" (in the second case, bash will answer
that the "ls -l" command does not exist" ;
2. the environment variables are evaluated by the shell, ant WILL NOT
evaluate them. <arg value="$PATH"/> will send a literal $PATH as an
argument. $PATH will NOT be interpolated by ant at all.

The only means of doing what you want is to write a shell script to
echo the value of the PATH environment variable.
