Fixed uninitialized variables for the '/'-in-pathname case in execvp().

Browse source 
Garbage in `eacces' caused the wrong errno to be set for non-EACCES errors.
Garbage in `etxtbsy' caused a semi-random retry strategy for ETXTBSY errors.

Found by:	NIST-PCTS.  gcc -Wall reported the problem, but -Wall is not
		enabled for libc.
