[COMMITTED] a68: avoid conditional expression in sppp.awk

[Jose E. Marchesi]

The macOS awk seems to not like having an unparenthesized conditional
expression as the last argument to printf.  This commit workarounds
this by simply replacing the conditional expression with a conditional
statement.

Tested with gawk and mawk.
