scripts: Remove setting of PATH from functions file
The current setting is inconsistent with settings on most systems,
putting /bin before /sbin. Use of /usr/local/bin, which may be
required on some systems, is also overridden. This can make it
difficult to do interactive debugging of script problems.
Rely on the system PATH instead.
If system-specific changes need to be made then this can be done in a
configuration file.
