pgrep: fix -x option
Because when -x is used (exact match), then we cannot compile the
regular expression with REG_NOSUB. The manual page regcomp(3) states
in section "Byte offsets":
Unless REG_NOSUB was set for the compilation of the pattern
buffer, it is possible to obtain substring match addressing
information.
The problem was detected on an ARM system with glibc 2.16.
