NCS based unknown Kconfig symbols

[JordanYates]

When using Memfault with standard Zephyr, there are several symbols which fail Kconfig linting (compliance is hinted at in #102 (comment))
MODEM_JWT and NRF_CLOUD_COAP_MAX_USER_OPTIONS don't exist in either Memfault or Zephyr (defined in NCS).

warning: undefined symbol MODEM_JWT:

Thanks @JordanYates for reporting these issues! We'll be fixing them in the next SDK release, scheduled for sometime later this week

See other issues, this is fixed in Memfault SDK 1.37.1.
