Update bdi->capabilities assignment due to change in the value semantics

Commit kernel-4.18.0-361.el8~13^2~6 ("bdi: replace
BDI_CAP_NO_{WRITEBACK,ACCT_DIRTY} with a single flag", upstream commit
f56753ac2a90) has changed the semantics of bdi->capabilities without
any oracleasm-tangible kABI effect (by virtue of being a change of macro
values;  the accompying function change has not have any effect as oracleasm
kmod doesn't utilise any of them).  Update the capabilities value to a new one.

* 0004-update-bdi-writeback-acct_dirty-flags.patch: New file.
* kmod-redhat-oracleasm.spec (kmod_rpm_release): Bump to 13.
(kmod_kernel_version): Bump to 4.18.0-369.el8.
(kmod_kernel_version_min): Bump to 4.18.0-361.el8.
(Patch4): New patch.
(%prep): Apply it.
(%changelog): Mention it.
