[2/2] livepatch-tools: fix isnumber() function clash

Commit Message

Roger Pau Monne Nov. 13, 2023, 4:09 p.m. UTC

isnumber() is already defined for some libcs [0] but the interface is not the
same, the isnumber() helper just checks if a single character is a digit.

Rename isnumber() to is_number() in order to avoid the clash.
