lib/bootconfig: use size_t for strlen result in xbc_node_match_prefix()

lib/bootconfig.c:198:19: warning: conversion from 'size_t' to 'int'
may change value [-Wconversion]
lib/bootconfig.c:200:33: warning: conversion to '__kernel_size_t'
from 'int' may change the sign of the result [-Wsign-conversion]

strlen() returns size_t but the result was stored in an int. The value
is then passed back to strncmp() which expects size_t, causing a second
sign-conversion warning on the round-trip. Use size_t throughout to
match the API types.
