oeqa/selftest: lock down Meson git revision for reliability
The test_recipetool_create_github test fetches HEAD of the repository so
upstream changes can (and do) break the test. Avoid these problems by passing
the rev= argument in the URL to lock the checkout to the same version that is
fetched in the github_tarball test.
Also pass the commands to runCmd() as a list instead of a string, the semicolon
in the URL needs more quotes if the shell is involved and passing a list
bypasses the shell entirely.
