Qualys Security Advisory efae601c3c 0047-proc/whattime.c: Always initialize buf. ...

In the human_readable case; otherwise the strcat() that follows may
append bytes to the previous contents of buf.

Also, slightly enlarge buf, as it was a bit too tight.

Could also replace all sprintf()s with snprintf()s, but all the calls
here output a limited number of characters, so they should be safe.

---------------------------- adapted for newlib branch
. the source file is now proc/uptime.c
. function is now named 'procps_uptime_sprint()'
. new human readable function 'procps_uptime_sprint_short()'
. both were already initialized, so just raised size of 2 buffers
