bitbake.conf: Remove PR glob part from STAMPCLEANHEADmaster

Since OE-Core rev: cc83e45484656a6b577ff84817131735023daad4
the STAMP value and STAMPCLEAN glob have been mismatched. The
issue is present since the PR part was removed from the STAMP variable
in that comit.

An example use case that I found was broken due to this:

1. Have recipes foo_A.bb and foo_B.bb
2. Build foo-native with PREFERRED_VERSION_foo-native = "A"
3. ${COMPONENTS_DIR}/x86_64-linux/foo-native has version A
4. Build foo-native with PREFERRED_VERSION_foo-native = "B"
5. ${COMPONENTS_DIR}/x86_64-linux/foo-native has version B
6. Build foo-native with PREFERRED_VERSION_foo-native = "A"
7. ${COMPONENTS_DIR}/x86_64-linux/foo-native still has version B

In my case the PREFERRED_VERSION comes from different machines.
The issue showed itself when a bar-native compiled against foo-native
version A was pulled from sstate-cache and foo-native in version B was
kept in ${COMPONENTS_DIR} after previous build for a different machine.

The two variables should be in sync and this patch corrects that.
