TPM Sysfs jobs all refer to a seemingly nonexistent resources scrip

[bladernr]

Bug Description

While trying to see if we have a programmatic way to determine if a TPM exists on a machine, I looked at the TPM jobs in the base provider. I discovered that in providers/base/units/tpm/ there's a sysfs.pxu that lists several jobs that are supposed to get data from sysfs about installed TPMs.

Several of those seem to depend on a script called tpm_sysfs_resource.py, but that script does not seem to exist in checkbox.

bladernr@galactica:~/development/checkbox/providers$ grep -r tpm_sysfs_resource.py
base/units/tpm/sysfs.pxu: tpm_sysfs_resource.py tool. The only resource attribute is 'count'
base/units/tpm/sysfs.pxu:command: echo "count: $(tpm_sysfs_resource.py | grep -c -F 'x-sysfs-device-name')"
base/units/tpm/sysfs.pxu:command: tpm_sysfs_resource.py
base/units/tpm/sysfs.pxu:command: tpm_sysfs_resource.py
base/units/tpm/sysfs.pxu:command: tpm_sysfs_resource.py
bladernr@galactica:~/development/checkbox/providers$ find . -name tpm_sysfs_resource.py
bladernr@galactica:~/development/checkbox/providers$ 

For example:

unit: job
id: sysfs_tpm_count
category_id: tpm
plugin: resource
_summary: Count the number of visible TPM chips in sysfs
_description:
 This job just counts the number of visible TPM chips in as reported by
 tpm_sysfs_resource.py tool. The only resource attribute is 'count'
command: echo "count: $(tpm_sysfs_resource.py | grep -c -F 'x-sysfs-device-name')"
estimated_duration: 2s
flags: preserve-locale

How are these jobs ever run if that script doesn't exist? Is it stored somewhere outside of checkbox, perhaps?

To Reproduce
