[12/17] maven git commit: [MNG-5852] mvn shell script invokes /bin/sh but requires Bash functions

[hb...@apache.org]

[MNG-5852] mvn shell script invokes /bin/sh but requires Bash functions

'local' is not POSIX, but supported by most shells. However, it's not
supported by Solaris's /bin/sh, so use a subshell instead.

This closes #50.
