Remove unused variable

X509_NAME_print() is documented to print things at a given indentation
level. Unfortunately, this never worked since someone got some logic
wrong. Part of the wrong logic was removed in a dead code removal in
OpenSSL commit 92ada7cc, but the variable l was left behind, which leads
to compiler warnings on some platforms. End its sad life pointlessly
and incorrectly measuring column width and remove it.
