Handle change in path for udisks2-inhibit executable (!84)

Debian (and derived) distros with the udisks2 [1] repository and the
additional 'udisks2-inhibit' executable had the location changed from:
    /usr/lib/udisks2/
to:
    /usr/libexec/udisks2/
with udisks2 version 2.8.4-2 and the following commit:

    f6744a33 - Move the daemons to /usr/libexec now that's allowed in the policy
    f6744a3364

Distros such as Fedora and openSUSE are unaffected as the udisks [2]
repository does not contain 'udisks2-inhibit'.
