nvme-print: sanitize supported-log-pages output

The current nvme supported-log-pages output is a little cryptic
as seen below:

Support Log Pages Details for nvme1n1:
LID 0x0 (Supported Log Pages), supports 0x3

LID 0x1 (Error Information), supports 0x3
...

So sanitize this output to make it more meaningful with better
formatting. This should apply to the verbose output as well.
With these changes, the sanitized normal output should show up
as follows:

Support Log Pages Details for nvme1n1:
LID 0x0 - Supported Log Pages
LID 0x1 - Error Information
...

And the sanitized verbose output would show up as:

Support Log Pages Details for nvme1n1:
LID 0x0 - Supported Log Pages
  LSUPP is supported
  IOS is supported
LID 0x1 - Error Information
  LSUPP is supported
  IOS is supported
...
