build: remove dependency on org.jlab.coda:jtools

[c-dilks]

For reference, here's a decompilation of the jtools JAR from clasweb (you must be signed in):
https://code.jlab.org/dilks/jarchaeology-jtools

jtools is only consumed by our

common-tools/clas-reco/src/main/java/org/jlab/clas/reco/Clas12Types.java

where it's used for 2 things:

1. org.jlab.clas12.tools.MimeType

We only use MimeType.EVIO.type() which returns the string "binary/data-evio", and is the only place where we don't hard code such a "binary/data-*" string; so, let's just hard code it to avoid the dependency.

Note

In theory, we could add such "binary/data*" strings upstream in clara-java's enumerator in

src/org/jlab/clara/engine/EngineDataType.java

along its other "binary/*" strings, or similarly in xmsg's

src/org/jlab/coda/xmsg/data/xMsgMimeType.java

but we've forked those and probably should avoid diverging from their upstream repos too much...

2. org.jlab.clas12.tools.property.JPropertyList

Used in PROPERTY_LIST, which is unused, so we can just remove it.
