doc: remove run.md markdown

Commit 93cea25de551 ("test: Port tpmclient into the integration test
framework.") added the tpmclient to the tpmclient to the integration
test harness, so now is executed as part of the make check target.

Since tpmclient isn't supposed to be executed as standalone anymore,
the run.md markdown document becomes outdated and should be removed.
