[bug] incompatibility between eg25-manager and gnu-grep

[DrYak]

This packages installs the udev rule /lib/udev/rules.d/80-modem-eg25.rules which contains the following sub part:

# Special trick for the PinePhone Pro: set power/persist to 1 *only* with the community FW
# We can identify the PPP by looking for the string "pinephone-pro" in the device tree "compatible" property
ATTRS{idVendor}=="2c7c", ATTRS{idProduct}=="0125", PROGRAM=="/bin/grep pine64,pinephone-pro /proc/device-tree/compatible", ATTR{power/persist}="1"

This works with package busybox-grep because the dispatcher symlink is stored indeed in /bin/grep.
This breaks with package gnu-grep as that one puts its binary in /usr/bin/grep.
