fs/procfs: Print the uptime with integers in all configurations.
With CONFIG_LIBC_FLOATINGPOINT on, /proc/uptime computed its one number in
double. On a CPU with no FPU this pulls in soft-float code that the rest of
the image may not need. The integer path gives the same format: 7 digits,
a point and 2 digits.
Delete the double path, so that all configurations use the integer path.
