app/testpmd: compact RSS types output
In port info command output, 'show port info all', supported RSS offload
types printed one type per line, and although this information is not
most important part of the command it takes big part of the command
output.
In port RSS hash and flow RSS command output, 'show port 0 rss-hash',
and 'flow query 0 0 rss', all enabled RSS types are printed on one line.
If there are many types, the print will be very long.
Compacting these RSS offloads and types output by fixing the length of
the character string printed on each line, instead of one per line or
one line.
Output becomes as following:
Supported RSS offload flow types:
ipv4-frag ipv4-tcp ipv4-udp ipv4-sctp ipv4-other
ipv6-frag ipv6-tcp ipv6-udp ipv6-sctp ipv6-other
l4-dst-only l4-src-only l3-dst-only l3-src-only
