trace: apps/openssl: print the correct category name
Previously, if the openssl application was run with OPENSSL_TRACE=any,
all trace output would just show 'ANY' as the category name, which was
not very useful. To get the correct category name printed in the trace
output, the openssl application now registers separate channels for
each category.
The trace API is unchanged, it is still possible for an application to
register a single channel for the 'ANY' category to see all outputt,
if it does not need this level of detail.
