Fix intersection with glibc personality()

On Linux we have glibc personality() - wrapper to linux
personality syscall. But used in ps 'personality' global
variable leads to personality() function pointer overwrite.
It leads to segmentation fault error on personality() usage.
Such call could be done in dependent libraries or in preloaded
library. E.g. when gcc address sanitizer is used we have
error on libasan.so initialization.

This patch fixes the error by changing intersected global
variable name to "_personality"
