smartcard: Use a more user friendly reader name
With that we get
PIN code for L5 built-in SmartCard Reader 00 00:
for pin prompt and for --card-status
:
$ gpg --card-status
Reader ...........: L5 built-in SmartCard Reader 00 00
Application ID ...: D2760001240103030005000091000000
Application type .: OpenPGP
Version ..........: 3.3
Manufacturer .....: ZeitControl
rather than
PIN code for TTXS serial 00 00:
which doesn't give much information in case of multiple SC readers.
@angus.ainslie librem5-devkit-tools test's don't use the old reader name but maybe the factory floor tests do?
