do not override systemd restart config options

There doesn't appear to be any special reason for this service to
override the defaults set by OpenBMC for how many times a service should
restart before giving up.

Recently we saw an issue where this service was failing repeatedly. It
continued to just loop and loop on restarts, generating core dump after
core dump. The whole purpose of the restart limits is to avoid
situations like this.

Tested:
Verified that this change caused srvcfg-manager service to stop after
failing twice
