recipetool: create: fix conflict between SRCREV and tag

If you specify 'tag=' for a git URL and passed to recipetool create, you
will get into Bitbake expansion error shown below:

----- snip -----
$ devtool add --version 2.4.2 mbedtls "git://github.com/ARMmbed/mbedtls;tag=mbedtls-2.4.2"
...
bb.data_smart.ExpansionError: Failure expanding variable SRCPV, expression was ${@bb.fetch2.get_srcrev(d)} which triggered exception FetchError: Fetcher failure: Conflicting revisions (abeccb9dbd7e19ae91ac50e1edd3803111c5f9b6 from SRCREV and mbedtls-2.4.2 from the url) found, please specify one valid value
----- snip -----

Assuming the tag is valid, we should get the tag commit hash and
drop the usage of 'tag=' from SRC_URI. By using a commit hash
corresponding to the tag will prevent bitbake from accessing
remote repository in order to expand SRCPV.
