Most modules appear to have their man pages stored alongside their source code.

However, the jfr man page appears to be in java.base, instead of the jdk.jfr module.

If this is deliberate, could someone please explain why? If not, I propose moving the jfr.1 file into the right directory.

Test: a test build produced the correct results.

History: The jfr.1 file was added to jdk13 by this bug:
https://bugs.openjdk.java.net/browse/JDK-8228494
No indication whether the jfr.1 file was added deliberately or not.
