updating path to prefer /sbin

[anthonysomerset]

Pull Request (PR) description

RHEL has a consolehelper based wrapper around subscription-manager at /bin/subscription-manager used for elevating permissions gracefully and interactively - something not available within a puppet run

The real subscription-manager binary is available at /sbin/subscription manager (or more correctly perhaps - /usr/sbin/subscription-manager

for some reason or another likely path ordering when running from within puppet the subscription-manager exec can fail with no output

when disabling the "Sensitive" around the exec you would get this error:

Notice: /Stage[main]/Rhsm/Exec[RHSM-register]/returns: Traceback (most recent call last):
Notice: /Stage[main]/Rhsm/Exec[RHSM-register]/returns:   File "/bin/subscription-manager", line 9, in <module>

Notice: /Stage[main]/Rhsm/Exec[RHSM-register]/returns: ImportError: Entry point ('console_scripts', 'subscription-manager') not found

which notes the use of /bin/subscription-manager - this PR explicitly sets the exec to use /sbin/subscription-manager for more reliability
