net-snmp: Reproducibility: Don't check build host for /etc/printcap

Don't check for /etc/printcap on the build machine when cross-compiling.
Use AC_CHECK_FILE to set the cached variable ac_cv_file__etc_printcap instead.
When cross-compiling, this variable should be set in the environment to "yes" or
"no" as appropriate for the target platform.

I have taken the simple expedient of setting ac_cv_file__etc_printcap=no.
If this proves to be a problem, we can easily add a new variable, HAS_PRINTCAP.
