[packman] jackdmp 64-bit rpm: lib or lib64

[Norbert Schmidt]

Hello,

thanks for packaging 0.62-0.pm.2 that fast.

Trying another arch (where I want to run it actually), 
but found another issue to fix:

Installing jackdmp-0.62-0.pm.2.x86_64.rpm install-scripts work fine 
in /usr/lib64, but:

~> jackdmp -R -v -dalsa
could not open driver directory /usr/lib/jackmp: No such file or directory

jackdmp: no drivers found; exiting


Linking to /usr/lib64/jackmp respective /usr/lib64/libjack.so.0 seems
to repair 64-bit-package.

(hopefully no further build (arch) problems).

Norbert
