te_macros: remove print macro

aosp/605217 adds the following lines:
genfscon tracefs /options/print-tgid u:object_r:debugfs_tracing:s0
genfscon debugfs /tracing/options/print-tgid u:object_r:debugfs_tracing:s0

However, the m4 pre-processing step of selinux policy compilation outputs:
genfscon tracefs /options/-tgid u:object_r:debugfs_tracing:s0
genfscon debugfs /tracing/options/-tgid u:object_r:debugfs_tracing:s0

And as a result of the "print" it prints:
m4: system/sepolicy/private/genfs_contexts: 177:
m4: system/sepolicy/private/genfs_contexts: 203:

Due to the following macro:
https://android.googlesource.com/platform/system/sepolicy/+/oreo-mr1-dev/public/te_macros#580

This change removes the now-deprecated print macro to unblock
aosp/605217.

Bug: 72862003
Test: verify that the m4 output for aosp/605217 is correct.
