patch 9.1.1789: MS-Windows: using wrong check for bold font

Problem: MS-Windows: using wrong check for bold font
(after v9.1.1347)
Solution: Test if lf.lfWeight == FW_BOLD instead of a simple truthiness
test (Shay)

Commit 411ae58 replaced an operator conditional

`if lf.lfWeight == FW_BOLD`

with a truthiness check

`if lf.lfWeight`

This conditional determines whether `:b` is inserted into the value of
`guifont`. The truthiness check allowed both FW_STANDARD and FW_BOLD
font weights to trigger the insertion of `:b` into the `guifont` string.
This commit restores the `== FW_BOLD` condition.

fixes: #18383
closes: #18397
