[OE-core][scarthgap][PATCH 2/2] libpcre2: fix RunGrepTest Failure on Busybox systems

The PCRE2 RunGrepTest script uses the Gnu Coreutils form:
head -1

Busybox does not support this shorthand option and reports:
head: invalid option --'1'

which cause the grep tests fail when running ptest on yocto.
Replace head -1 with head -n 1 . This makes RunGrepTest work
correctly.
