bitbake: bitbake-user-manual-ref-variables: Update the help for BBMASK

contain multiple regular expressions. Also changed the examples for
BBMASK to be a bit more diverse.

you can specify multiple regular expression fragments.
This next example masks out multiple directories and
individual recipes:
<literallayout class='monospaced'>
BBMASK = "meta-ti/recipes-misc/|meta-ti/recipes-ti/packagegroup/"
BBMASK .= "|.*meta-oe/recipes-support/"

BBMASK .= "|.*opencv"

BBMASK += "opencv.*\.bbappend"
BBMASK += "lzma"
</literallayout>
Notice how the vertical bar is used to append the fragments.
<note>
When specifying a directory name, use the trailing
slash character to ensure you match just that directory
